Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2)) "release 139"
Qt Version: 4.5.1
Operating System: Linux 2.6.27.23-0.1-default x86_64
Distribution: "openSUSE 11.1 (x86_64)"

What I was doing when the application crashed:
When I open Sunbird and use the Provider for Google Calendar addon this bug report comes up. No functional operations are lost that I can see.  I was able to add & remove a plasmoid, also the plasmoids I do have work well.
 This seems to be more of an annoyance than a problem.
If there are any further questions I'll answer them.
