Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1) "release 6"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-0.1-pae i686

What I was doing when the application crashed:
Sometimes the crash happens after starting kmail per contact. However, I don't see any effect neither on the desktop appearance nor on an application. The only reason I get notice about the crash is the popup crash notification window. The crash happens only once during the session. No known further regression. The current version Suse 11.2 was upgraded by me from 11.0 to 11.1 to 11.2 manually. This means, I changed the repositories in Yast just by renaming the old names and using zypper for an upgrade. To get the difference to a new installation, I installed Suse 9.10 in a second partition from the scratch. There was (up to now) no such a problem as described above, however, I didn't use Kmail yet.
