-- Information about the crash:
I have two screens, and if I turn one of them or both off and I turn them on again, often plasmashell crashes, but not every time. I believe it's a timing issue, where it won't crash if I wait until it has moved all windows to one screen, but if I turn it on while it's moving windows to the single screen it crashes.

The crash can be reproduced sometimes.
