Bug 317348

Application: systemsettings (1.0)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-17-generic x86_64
Distribution: Linux Mint 14 Nadia

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

Creating a new user account, non-admin, and out of nowhere, the crash screen slapped me in the face... the user accounts module didn't even close, and is still active.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
