[Comment from a bug report cleaner]
Hint: the crash is related to the Python scriptengine.
- Which third-party widgets do you have installed in your system ?
Thanks

bug in the python bindings. several samplings of these problems have been forwarded on to the bindings team. this feature set is not maintained by the core plasma team, however, so marking as 'upstream' as the closest accurate resolution.
