Bug 195424

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.88 (KDE 4.2.88 (KDE 4.3 >= 20090527)) "release 127"
Qt Version: 4.5.1
Operating System: Linux 2.6.27.21-0.1-default i686
Distribution: "openSUSE 11.1  (i586)"

What I was doing when the application crashed:
I began to answer a post in knode, then decided not to finish it and cancelled the partly written answer. Plasma crashed, _not_ knode. Plasma restarted again after the crash.

 -- Backtrace:
