Bug 222238

Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
plasma crashes when the sending dialog in thunderbird closes. It's not always the case but it occured to me more than three times in KDE 4.4 beta 2 and also in RC 1.
I'm not sure whether it's related to bug #210146.

I use the the kubuntu ppa packages.

The crash can be reproduced some of the time.

 -- Backtrace:
