Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1))
Qt Version: 4.5.1
Operating System: Linux 2.6.30-cs-1-intel-kms x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
This plasma-desktop crash often happens whilst I'm away from this system for a while, so appears unrelated to any activity of mine.

My system is running the weather wallpaper plugin as well as the following plugins:

$ fgrep plugin ~chris/.kde/share/config/plasma-desktop-appletsrc
plugin=desktop
wallpaperplugin=weather
wallpaperpluginmode=
plugin=weather
plugin=folderview
plugin=folderview
plugin=luna
plugin=weatherstation
plugin=systemloadviewer
plugin=fileWatcher
plugin=twitter
plugin=panel
plugin=notifier
plugin=networkmanagement
plugin=digital-clock
plugin=lockout
plugin=launcher
plugin=quickaccess
plugin=tasks
plugin=pager
plugin=showdashboard
plugin=systemtray

Hope this helps!
