Comment 1 Christof Debaes 2010-07-08 13:57:47 UTC

Repeating the same procedure did not cause a crash afterwards. I did notice this behaviour once in 4.4.4 as well.

New crash information added by DrKonqi

krunner (0.1) on KDE Platform 4.4.92 (KDE 4.4.92 (KDE 4.5 RC2)) using Qt 4.7.0

- What I was doing when the application crashed:

Krunner crashes randomly after completing the command entered.
