Bug 238337

Application: plasma-netbook (0.1)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I'm using Kubuntu 10.4 amd64.

This happened twice in a row today, but it has happened before on this machine.

I searched for "paint" to find an applikation for paint a simpel drawing and it gave no results and when plasma crashed.
It happened again right after plasma restarted, when I tried again.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Plasma Netbook (kdeinit4), signal: Segmentation fault
