Bug 236203

Application that crashed: systemsettings
Version of the application: 1.0
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-trunk-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
I started systemsettings, clicked the "PolicyKit" option, and then, systemsettings always promptly crashes without *any* activity.

 -- Backtrace:
Application: Nastavení systému (systemsettings), signal: Aborted
