Qt Version: 4.8.4
Operating System: Linux 3.4.28-2.20-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
Upgraded Lenovo ThinkPad Edge E530 from KDE 4.8.5 to 4.10 (OpenSuSE 12.2).
Upon KDE Startup (after login) the plasma desktop segfaults. This happens both in normal and in safe mode.

The crash can be reproduced every time.
