KDE Platform Version: 4.4.2 (KDE 4.4.2) "release 238"
Qt Version: 4.6.2
Operating System: Linux 2.6.27.45-0.1-pae i686
Distribution: "openSUSE 11.1 (i586)"

-- Information about the crash:
When I tried to find some widget by using the search bar of the Add Widget applet, the applet crashed after typing the letters "an".

The crash does not seem to be reproducible.

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