Application: systemsettings (1.0)
KDE Version: 4.3.75 (KDE 4.3.75 (KDE 4.4 >= 20091113)) (Compiled from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Whenever I try to open Remote widgets' policies from System Settings, System Settings crashes with the attached backtrace. From the bugtrace I suppose it has something to do with KAuth / polkit-qt. However, when I open Login Manager (anothe module that needs auth), it loads without crashing but also in non-root mode without asking me for authentication. 

 -- Backtrace:
