-- Information about the crash:
- What I was doing when the application crashed:
I plug and unplug a device, plasma, knotify and krunner crash with similar backtraces.
This happens every time I unplug (not when I plug in). plasma-desktop backtrace attached.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Aborted
