Attachments: New crash information added by DrKonqi

Description cataclysmorama+kdebugs 2012-04-30 14:06:15 UTC 
Application: krunner (0.1)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.2.0-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:
After pressing ALT+F2, I typed in "remmina" to open said program. When pressing the enter key, krunner crashed.
It should be noted that the pop-down menu wasn't open when I pressed enter, so krunner might not have chosen a menu entry from there.

After trying again (with the same command), krunner works without crashing.
Pop-down menu opens immidiatly.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Oberfläche zur Ausführung von Befehlen (krunner), signal: Aborted

Comment 1 Christoph Feck 2012-04-30 17:38:47 UTC 
The crash is caused by the "WindowsRunner" doing X11 calls in the non-UI thread.
