Description smalcom 2010-09-24 08:43:58 UTC

Application: plasma-desktop (0.4)
KDE Platform Version: 4.5.69 (4.6 >= 20100920)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-gentoo-r5.sm1 x86_64

-- Information about the crash:
- What I was doing when the application crashed:

Add typical panel and they placed at top of screen.
After that: "Add widget" on top panel and grey stripe without widgets was drawed.
After that i do "Lock widget", "Unlock widget", "Add widget".
Thats all

The crash does not seem to be reproducible.

Bug 252298 seems to have a similar backtrace, could it be a similar issue ?
