Description Marcus Harrison 2009-12-30 01:31:49 UTC

Application: krunner (0.1)
KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
Usign the spell-checker runner sometimes results in a freeze or crash of KRunner. This most prominently occurs with the spell-checker runner, though sometimes slow-downs and freezes are noticed in other areas as well.

The crash can be reproduced some of the times.

 -- Backtrace:
Application: Run Command Interface (krunner), signal: Segmentation fault
