Thank you for the bug report. Based on the backtrace this looks like a duplicate of bug 506642 so I'll merge this report in with the other one. Please follow that report if you would like updates on the progress of this issue.

*** This bug has been marked as a duplicate of bug 506642 ***

Possibly.
However in my case I did not use Quick Settings today (as described in the other bug report) and Plasmashell crashed anyway.

It's common for the same crash to be able to be produced in different ways. The thing that confirms these are the same crash is the backtrace.
