-- Information about the crash:
- What I was doing when the application crashed:

I had just rebooted with my android phone plugged in.  The phone is set to PTP mode.  When I tried to download the photos with digicam, the machine hung up briefly, then appeared to open multiple digicams.  Then plasma-desktop crashed.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
