Bug 325932

Application: plasma-desktop (4.11.1)
KDE Platform Version: 4.11.1
Qt Version: 4.8.3
Operating System: Linux 3.5.0-40-lowlatency i686
Distribution: Linux Mint 14 Nadia

-- Information about the crash:
- Had just placed the printer widget and was inspecting my settings and information. Crash, and plasma crashes now on every attempt to reload.

- Custom settings of the application: I may have been trying to view the print queue.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
