Description Thomas Thym 2009-05-19 12:55:38 UTC
Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.86 (KDE 4.2.86 (KDE 4.3 >= 20090514)) "release 125"
Qt Version: 4.5.1
Operating System: Linux 2.6.25.20-0.1-pae i686

What I was doing when the application crashed:
Plasma crashed while I was playing around with some widgets. e. g. I closed Bubblemon and added Yasp). The system was very slow bevore and I wanted to check RAM, etc. So perhaps it has nothing to do with those two widgets.

Comment 1 Thomas Thym 2009-07-05 14:48:41 UTC
Still crashing with 4.2.95. This time locking the widgets.

No idea if this is a dup of https://bugs.kde.org/show_bug.cgi?id=176014

Comment 2 Sebastien Martel 2009-07-15 23:08:56 UTC
Just wanted to verify if this was a problem with the system monitoring applet or ksysguard since they are two different application, from reading your report it seems to be a problem with the plasma widget.  Could you confirm?
Comment 3 Thomas Thym 2009-08-30 11:44:41 UTC
Seems to be fixed. No problems in 4.3.0 anymore.
