Description Waldemar Haag 2010-11-02 09:55:19 UTC
Application: krunner (0.1)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.36-0.dmz.4-liquorix-amd64 x86_64
Distribution (Platform): Debian unstable

-- Information about the crash:
I was typing "kdesu kate" in the window that pops up with "Alt+F2" when the window suddenly froze. It didn't react to everything I tried to do, and then it crashed. I tried it another time, and now it didn't crash but just didn't react at all. I was kind of annoyed, so I killed the window with "Ctrl+Alt+Esc", but after that I wasn't able to open it again with "Alt+F2" until I restarted kde.
I'm using a version of Sidux "Keres" that I installed 2 days ago.
I hope this information is useful to you =)

The crash can be reproduced every time.

Comment 1 Waldemar Haag 2010-11-02 16:58:03 UTC
It seems that this problem only occurs if I need too much time to type the command. If I hurry up it works without problems.
Comment 2 Matthias Fuchs 2011-01-26 21:08:30 UTC
This looks like a Qt bug to me. Please reopen if this happens again with Qt 4.7.
