Crash log

Not always, but very frequent, workrave crashes after the rest break count down.

It seems Workrave crashes when showing exercises. What language are you using?

> It seems Workrave crashes when showing exercises. What language are you using?

Well I have done a lot of the exercises, so it is capable of showing them. The last few crashes (which I haven't filed as bugs, since I think it relates to this one) occured when I press 'postpone' and when the restbreak counter finishes, the program crashes.

At first I used Danish as language, since this it what my system is running. But I have switched to English now, hoping for a more stable program (an old habbit of presuming English being more stable than a small language).

In the past, corrupt translation files have caused crashes when displaying the exercises. I haven't been able to find a any problems with the Danish translation.

If you have some other crash reports, please add the to this bug. I wonder if crashes occur at the same location every time (probably not. this crash seems to occur when the restbreak window was first opened)

You could also try:

http://snapshots.workrave.org/20110111/workrave-win32-v1_9_3-16-gbfb2206b99-20110111-installer.exe

This version uses a slightly more recent version of the Gtk library (and the crash appears to be inside this library).

Thanks!

I will try the proposed version at a later point. But if you want me to add more crash logs, I'll stay with my current version.

Crash log #3

This one happened after I had seen the exercises and wanted to go on working, thus clicking 'skip' on the ~9min break window.

Created attachment 230
Crash log #4

I got the first break reminder. When exercises began, I postponed.

I got the next break reminder. After the rest break reminder, just before the exercises, the crash came.

Thanks! The dump are very helpful.

It seems that none of the crashes occur at the same location. 3 out of 4 crashes occur during initialization of the exercises. Crash 3 occurs somewhere else (in Workrave's timer handler), but after the exercises were shown (according to comment #7). Two of the crashes occur when allocating memory. So I expect that the exercises cause some memory corruption....

Does Workrave also crash when you disable exercises? 

I'm also curious to hear if the latest snapshot from http://snapshots.workrave.org/  (e.g. http://snapshots.workrave.org/20110118/workrave-win32-v1_9_3-17-g0101db5baf-20110118-installer.exe) fixes the problem. Thanks again!

Crash log #5

This time the number of exercises was set to 0. 
I think I skipped a break and the crash occurred when/after the following break.

I am now switching to your last suggested version:

http://snapshots.workrave.org/20110118/workrave-win32-v1_9_3-17-g0101db5baf-20110118-installer.exe

I am curious to hear if Crash Log #5 where no exercises was shown tells you anything. 

I'll return if any crash occurs in the latest version.

Crash log #6

This time I postponed my break twice, and the third time the crash occurred just after the rest-break count down.

Created attachment 236
Crash log #7

Crash log #7 seems to be exactly the same as with Crash log #6.

In crash #5, Workrave crashes while it is updating its UI. Crashes 6 and 7 are exercises related.

The crash location is different each crash, which make tracking the bug more difficult. Also, Workrave seems to crash only for a few people (well, I only got a few reports...). So there must be a difference between your computer/workrave settings and mine. 

- Are you running 64 bit windows XP?
- I noticed you have the microbreak and sounds disabled. Does Workrave also crash with these enanbled?
- Does Workrave still crash if you (temporarily) remove all files from "c:/Documents and Settings/<username>/Application Data/Workrave"

(In reply to comment #14)
> - Are you running 64 bit windows XP?

No I'm using Windows XP Pro SP3 32bit.

> - I noticed you have the microbreak and sounds disabled. Does Workrave also

I have disabled the microbreak because I don't want to be disturbed that often. I will enable them to provide you with more crash logs ;)

> - Does Workrave still crash if you (temporarily) remove all files from

I'll try immediately.

Crash log #8

Crash log #8 "contains" the result of emptying the workrave directory under application settings.

Enabling microbreaks seems to work even though I skip all breaks that has occurred the last 4 hours.

So how is a microbreak connected to a rest break and an exercise?

Great. This is very helpful! You could set the time-between-breaks of the microbreak to 10 hours, until I fixed the problem.

> So how is a microbreak connected to a rest break and an exercise?

Not sure yet. My guess it has something to do with displaying the mainwindow/applet. Workrave has to skip 1 timer.

I finally managed to reproduce the crash on XP using the same settings as you are using. However, after enabling the microbreaks again, the crash remained. It seems that the 'mute audio on breaks' options was causing crashes. Could you please test a recent snapshot, eg.

http://snapshots.workrave.org/20110128/workrave-win32-v1_9_3-24-g1721580133-20110128-installer.exe

(commit 37544a23377e58ad00f8)

This problem should be fixed in 1.9.4. You can download it from:

http://sourceforge.net/projects/workrave/files/workrave/1.9.4/workrave-win32-v1.9.4-installer.exe/download

Please reopen this issue if you still see the problem in 1.9.4

Many thanks for all the help!
