[Comment from a bug triager]
From 267738 (KDE SC 4.4.5):
-- Information about the crash:
I pressed ALT+F2, typed "oper" into the command execution box, this was
automatically completed into "opera" with a grey "a" at the end, I pressed
enter, this crash wizard appeared.

- Could you check if you can repeat this crash on KDE SC 4.5.x or 4.6.x ?
Thanks

I tried it, can't reproduce it in any way on Plasma Desktop 4.7.3. This must have been fixed in the bugfixing frenzy on KRunner last year. Evan, Andres, if you can get a new backtrace on a newer version of Plasma/KRunner, that'd be awesome. Please re-open the bug then, I'll close it now as 'remind' - a reminder to you, OK?

Thanks for reporting!

Hi guys, thanks for fixing this.
I haven't experienced this nasty behavior in last two versions of Kubuntu. It must be fixed already.

My current environment:
Distribution: Ubuntu 11.10
plasma-desktop: 4:4.7.2-0ubuntu2
libqt4-core: 4:4.7.4-0ubuntu8
Operating System: 3.0.0-13-generic-pae
