Description Danny Auble 2009-09-08 21:21:31 UTC 
Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I Expand Group of xterms or anything in the taskbar that is grouped, and then I choose to Collapse Parent Group, and everything dies afterwards and restarts.  I had about 9 xterms open and then I only had 3 afterwards.

 -- Backtrace:

Comment 1 Dario Andres 2009-09-09 14:57:32 UTC 
- Does Plasma crashes again if you repeat the steps you mentioned ? Can you install the "kdebase-workspace-dbg" package and post a complete backtrace here? Thanks
Comment 2 Danny Auble 2009-09-09 18:21:06 UTC 
This one happened when I expanded the group...

Comment 3 Danny Auble 2009-09-09 18:26:46 UTC 
I can't seem to get past the crash now.  I am not sure why, but when I try to expand, the taskbar appears to sort of expand them, meaning only a few of the many appear, and then the desktop crashes and when it comes back up the group is back together again, every time I try I get this result.
Comment 4 Dario Andres 2009-09-09 18:41:11 UTC 
The second backtrace is bug 197664. 
Let's mark as NEEDSINFO until we get a backtrace of the first crash.
Thanks
Comment 5 Danny Auble 2009-09-09 18:44:10 UTC 
Dario, I just got it to happen again.  Let me know if you need any more info.
