Comment 1 Dario Andres 2010-04-07 14:01:23 UTC 
The crash seems related to the "Luna" widget (provided by plasma_applet_luna2.so, and that "2" could indicate it is not the official luna widget ?):

#7  0xa6839a48 in Luna::paintInterface(QPainter*, QStyleOptionGraphicsItem
const*, QRect const&) () from /usr/lib/kde4/plasma_applet_luna2.so

Also, the "plasma_applet_publictransport.so" ("Public Transport"?) widget seems to be involved...

- Did you install another version of the Luna widget ? (or , could you check with OpenSuse package contains "/usr/lib/kde4/plasma_applet_luna2.so" ? )
- Does this still happen if you uninstall the Public Transport widget?

Regards
Comment 2 Oliver Zimmermann 2010-04-07 14:07:02 UTC 
I had Luna2, CWP, punlic transport and comic installed. Now ist is only CWP 
and Luna2 and it works. Seems to be one of the others.
Comment 3 Dario Andres 2010-04-07 14:15:18 UTC 
According to the code:

#16 0xb6803922 in QGraphicsScene::drawItems (this=0x8135b50,
painter=0xbfd18c5c, numItems=6, items=0x887aa50, options=0x887c2c4, widget=0x0)
at graphicsview/qgraphicsscene.cpp:5188
#17 0xb67f2834 in QGraphicsScene::render (this=0x8135b50, painter=0xbfd18c5c,
target=..., source=..., aspectRatioMode=KeepAspectRatio) at
graphicsview/qgraphicsscene.cpp:1753
#18 0xa68ff23e in ?? () from /usr/lib/kde4/plasma_applet_publictransport.so

The PublicTransport widget is trying to render the scene (I think only Plasma is responsible of that), and then a null widget (widget=0x0) is going to be drawn, causing the crash.

Then, we could assume the PublicTransport widget is the faulty one...
Comment 4 Jonathan Thomas 2010-04-17 14:10:40 UTC 
Agreed. Please report this to the authors of the Public Transport widget at http://kde-look.org/content/show.php?content=106175
Thanks, and have a nice day.
