Bug 224273

Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-16-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
with fairly high frequency, plasma crashes when I close a window (e.g., after reading an email) when using Thunderbird 2.0.0.23. The only salvation is that the desktop rapidly resrtores itself .

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
