backtrace with debug symbols

Plasmashell crashed when unlocking the screen. I attached a backtrace with DrKonqui and automatically installed debug symbols.

I'm using three screens, one of them seems to report itself as off when going to standby. Plasma seems to think the screen is gone completely - when I unlock the session, windows are always in a wrong position as if the screen had disappeared in the meantime.
Therefore I think it might be related to https://bugs.kde.org/show_bug.cgi?id=408030
