Application: plasma-desktop (4.10.90)
KDE Platform Version: 4.10.90
Qt Version: 4.8.5
Operating System: Linux 3.10.0-2.gc5ad3f9-default i686
Distribution: "openSUSE 13.1 Milestone 3 (i586)"

-- Information about the crash:
- What I was doing when the application crashed: logging on to KDE desktop on openSUSE 13.1 milestone 3 32-bit. After the crash, Alt+F2 to get a command window, then entering "plasma-desktop" starts the desktop manually, and thesystem is stable.

The crash can be reproduced every time.

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