It seems that the widget you deleted was a detached widget("extender") from some panel widget (may be the calendar from a clock; or a notification).
- If you can reproduce the crash at will (or you experience this regularly), can you install the "kdelibs5-dbg" package and post a complete backtrace here? (you can get more information at http://techbase.kde.org/User:DarioAndres/Basic_Guide_about_Crash_Reporting ) Thanks
This happens once in a while; however, I installed KDE from an Ubuntu PPA, and I don't think it's possible to install debug symbols for it... https://bugs.launchpad.net/soyuz/+bug/156575 Figured out how to get the stack traces:

I got this crash the same way as in bug 227615 which I just filed, so they may be duplicates.
Fixed in KDE SC 4.4.1 and 4.5: bug 219194. Regards *** This bug has been marked as a duplicate of bug 219194 *** |
