Bug 287162

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
I can't be sure, but I might have been updating the machine when plasma crashed.


Of great annoyance is that when plasma restarted, it placed the taskbar in a different location (I place mine at the top) and plasma placed it *near* but not *at* the bottom.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault
