Application: krunner (0.1)

Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- Backstory

I have some custom scripts in my PATH, which look sorta like this:
#!/bin/sh
rdesktop -u X -d X -p - terminalserver.X.com -g 1680x1050 -k no

and are used to connect to various windows remote desktop sessions. Not necessarily a terminalserver. They are executable, and I have also added them as applications in the KDE Menu Editor. I launch these via the built-in KDE launcher widget thingy (Alt+F2). This usually works. 

The problem seems to be: Sometimes when i invoke Alt+F2 and start typing the name of one of my scripts, the launcher crashes while I am typing (before I try to launch my custom scripts). 

- What I was doing when the application crashed:

This time I had just updated a script, and had just clicked 'save' in the KDE Menu Editor after unchecking the "run in terminal" option. I tried launching it (via Alt+F2) for the first time after it was edited. And the application launcher crashed again while typing. The next time i tried Alt+F2 and typed the script name it worked normally and I could launch my script.

On a related note: Before using the build-in KDE launcher I had the popular Launchy app installed, which has similar functionality. It also seemed to crash sometimes while I was typing the name of any of my custom executable scripts. Could be related.

The crash can be reproduced some of the time.
