Bug 276084

Application: polkit-kde-authentication-agent-1 (0.99.0)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.6-0.5-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

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

Logged in at the beginning of the day. Had two popups about "policy prevents getting brightnes level", both cancelled. (Those popups have been annoying me forever.) Otherwise system has been idle, crash handler was up when I came back to it.

System is set to
PERMISSION_SECURITY="secure local"

The crash can be reproduced some of the time.

-- Backtrace:
Application: PolicyKit1-KDE (polkit-kde-authentication-agent-1), signal: Segmentation fault
