Bug 197261

Application that crashed: krunner
Version of the application: 0.1
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.0
Operating System: Linux 2.6.30-9-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I just wanted to report another textbox rendering related bug, and while i typed the command and some backspace, then this happened.

It was happened one time before too. Now i can't reproduce it again.

 -- Backtrace:
Application: Run Command Interface (kdeinit), signal: Aborted
