-- Information about the crash:
I have a projector that, when turned on, generates disconnected and connected events. No event is generated when the projector is turned off.

Sometimes when I turn the projector on, plasma crashes.

The crash can be reproduced sometimes.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault
