Hmm, no KDE code is implicated in the backtrace.

Can you reproduce the crash when removing any other widgets? Or only with that one?

I can't reproduce plasma crash. maybe this is an isolated case.

Darn. If you can't reproduce the crash and there's no indication of KDE code involved, I'm afraid this bug report isn't actionable. :( Please do re-open it if the issue happens again though.
