Description Martín Cigorraga 2010-05-11 21:09:19 UTC 
Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.33-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
That's it. Right after loging in I pressed ALT+F1 as sometimes do to open kickoff and start typing first three characters from an application name I wanted to launch.
Then, an strange thing happened: after introducing the first three letters nothing showed up so it was obvious 'something' was happening.
I clicked then in the search bar to edit the word I just entered - it was written ok, no need for any edit at all but since the application name didn't show up I think about cleaning the bar and retype the few letters.
I pressed Bakspace and nothing happens, pressed again the same, pressed one more time and everything blow up. Plasma crashed and recovered itself few moments later but my wallpapers from desktops 1, 2 and 4 were gone.
Gonna restart right now after submitting this report.

Best and thanks a lot for this great DE/WM that you make for all of us =)

can you try to reproduce it with more debug packages installed?
