Application: systemsettings (1.0)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-1.slh.4-aptosid-amd64 x86_64
Distribution (Platform): Debian unstable

-- Information about the crash:
drkonqi shows a lot of bugs about "systemsettings -> login screen -> crash" being related to authorisation.
But on my system the modules "Data & Time", "Login Screen" and "Permissions" crashes, when I double-click on them while having "Input Devices -> Mouse" configured to "Single-click to open files and folder" no matter if I am root oder luser.
If I configure to "Double-click to open files and folders" the modules can be opened with double-click.
If I configure to "Single-click to open files and folder" the modules can be opened with single-click.
So it seems to be more a qt-signal-handling problem than a authorisation problem...
