Comment 1 Dario Andres 2009-06-12 20:58:13 UTC
Yes, the backtrace indicate it crashed on the OpenDesktop widget. Try to install the "kdeplasma-addons-dbg" package and fetch a new backtrace (which will be hopefully more complete). Thanks
Comment 2 Stefan Gründel 2009-06-13 09:05:51 UTC
Reproduced the crash after installing "kdeplasma-addons-dbg":
