Sentry Crash Report:

Description Roger Pixley 2009-11-27 01:53:55 UTC 
Application that crashed: krunner
Version of the application: 0.1
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.6.0
Operating System: Linux 2.6.31-15-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Krunner has crashed multiple times when I am typing quickly or if I open one app and quickly reopen it to open another. The majority of times I'm typing quickly I am opening Konqueror and it crashes when the bookmark for the rekonq site comes up then the applications come in. Frequently (I can't actually remember a time it crashed when I was typing konqueror and this didn't happen) The results show a hit a space with nothing in it and another hit where the selected item is the second blank space. I'm currently running A pre rc Qt 4.6. I'll stablize on the RC and move to the 4.4 beta which ships next week and see if this continues. If it does stop I'll revist this bug and ask for it to be closed.

 -- Backtrace:
Application: Run Command Interface (krunner), signal: Segmentation fault
The current source language is "auto; currently c++".

Qt 4.6 issue.. fixed already... 
Note that KDE SC 4.3 + Qt4.6 was not tested properly...
