-- Information about the crash:
- What I was doing when the application crashed:
Initialized shutdown and it began closing all open programs.  Then it only displayed a black desktop, and the bug report appeared.  So nothing else was displayed during the bug and it happened during shutdown.

-- Backtrace:
Application: PolicyKit1-KDE (polkit-kde-authentication-agent-1), signal: Segmentation fault
