Description Lilian A. Moraru 2012-03-23 01:50:01 UTC 
Application: krunner (0.1)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
This happened for the third time. I was writing some Java code in NetBeans with Firefox opened(in Firefox 1000+ opened tabs but with "Don't load tabs until selected" option activated), Firefox consuming ~600 MB Ram and Java consuming ~600 MB(I have 8 GB of RAM), none of them going over 1%-2% in processor usage. First time, I left it for a few minutes(NetBeans selected) and when I came back and tried to do something the screen wasn't responding well, lagging, closed Firefox and it started to work better, opened it back and after a while(~1 hour) it started to lag again(I checked and none of the applications was leaking or something like that, no processor usage increase...) and I was logged out. The second time I dimmed the screen(the special key on the laptop that turns off the screen), came back after ~1 minute and undimmed it and I observed that NetBeans was maximizing and minimizing fast and wasn't responding to my clicks with the mouse. Alt + Tab was working OK. I pressed Ctrl + Alt + F1 and wrote "sudo service kdm restart" but it freezed and I had to shut down forcedly. On boot KDE said that KRunner crashed... I never had that before... I also never had problems with Firefox at all.

- Unusual behavior I noticed:
The minimizing and maximizing was really strange. If I am not wrong Firefox was doing the same.

The crash can be reproduced some of the time.

New crash information added by DrKonqi

krunner (0.1) on KDE Platform 4.8.1 (4.8.1) using Qt 4.8.0

- What I was doing when the application crashed:

This crash happens after doing ALT-F2 to search for kopete and try to run it.
my krunner is configured for task oriented display.
