Workrave freezes after I upgrade to Ubuntu 9.4.

First I noticed that the applet counter was frozen. Then when killing the process and restarting, every time it went for a break (rest breaks or min-breaks), the clock stopped on either the count down time, or when forcing the break, it stops after a few seconds into the break.

I have also tried reinstalling workrave without success.

My apologies for the rush in passing on the bug, without having much detail on it.

Now I know exactly where the bug relies. 

I had a problem in the sound system, and every time workrave would play a little noise, it freezes the program. So it's not a issue with the Ubuntu, but with the program not being able to play the sound.
