Version of the application: 1.0
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.9-174.fc12.x86_64 x86_64

What I was doing when the application crashed:
I'm not 100% sure, but if I remember correctly KPackageKit crashed while importing a new sign key.

 -- Backtrace:
Application: Impostazioni di sistema (systemsettings), signal: Segmentation fault
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
