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: 4.5.0
Operating System: Linux 2.6.28-13-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I notice that plasma is periodically crashing.  At first I thought it might be related to the Weather Wallpaper.  I was receiving crashes when attempting to change the location for the weather to use.  However, I have recently been able to change the location with out crashes.
