Description Ioannis 2011-01-29 15:27:15 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic i686
Distribution: Ubuntu 10.10

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

The crash happens at start up. The crash happens every time plasma-desktop is launched. Something that maybe relevant is that I have 3 panels, each of them having a notification area. The various notifications are split accross those 3 panels.

The crash can be reproduced every time.

-- Backtrace:

plasma-desktop (0.4) on KDE Platform 4.7.40 (4.7.40 (KDE 4.8 >= 200110623) using Qt 4.7.1

- What I was doing when the application crashed:
Adding panel when plasma is started in Xephyr crashes it every time.

Notes:
Adding widgets works.
Background desktop image is not displayed - desktop background is simply painted black.

Comment 10 Artem 2011-06-27 19:32:11 UTC 
Well, actually adding widgets doesn't really work. I can add alarm clock,application launcher and some other to desktop, but I can't add systemtray to desktop.
Comment 11 Artem 2011-06-27 19:41:36 UTC 
Ok, more info.
Adding empty panel do works. And after I successfully added empty panel, I wasn't able to reproduce crash. No sure is this actually related.

Sounds weird, but that's all I have now.

Confirm on KDE 4.7.1 on Arch Linux.

Default panel crashes. Empty and Grouping panels are fine.
Comment 24 Dario Andres 2011-09-29 13:21:59 UTC 
[Comment from a bug report cleaner]
Bug 282552 also references crash related to a default panel, but related to the "QGraphicsLayoutItemPrivate::hasHeightForWidth" call
Comment 25 Chris 2011-10-17 00:03:22 UTC 
Also Confirm
