Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.10-1.9-default i686
Distribution: "openSUSE 12.1 (i586)"

-- Information about the crash:
- What I was doing when the application crashed: Intermittent Plasma Desktop crash and automatic recovery that seem to have developed after I set the taskbar to "Auto Hide".   Can't find a pattern, but it seems to happen when I move the pointer over the panel boundry to display or let it auto-hide.

The crash can be reproduced some of the time.

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