Description Ken 2011-11-18 16:17:11 UTC 
Application: polkit-kde-authentication-agent-1 (0.99.0)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

The pop-up to auto adjust brightness appears every 30 minutes or more asking for the root password. I see no purpose to the function for my environment so I always 'cancel' the pop-up. Sometimes (once a month or so) the PolicyKit crashes as it did here. After over a year of this and upgrading to SuSE 12.1 I decided to finally report it.

The crash can be reproduced some of the time.

polkit-kde-authentication-agent-1 (0.99.0) on KDE Platform 4.7.2 (4.7.2) "release 5" using Qt 4.7.4

Editing a php file in NetBeans. This is not the cause since this crash is random and has occurred when playing PySol or doing nothing.
