Bug 203981

Application that crashed: krunner
Version of the application: 0.1
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-14-server x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Launched krunner with ALT+F2
Typed in konsole
Hit enter before keywords populated
Krunner crashed.
Happens intermittently.
Does not impact relaunching krunner and using it.

 -- Backtrace:
Application: Run Command Interface (kdeinit4), signal: Aborted
