Sentry Crash Report:

Description Robert LeBlanc 2016-05-06 14:49:39 UTC 
Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.5.0-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (stretch)

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

I was going to put the laptop to seep after being on all night. The screen had moved to mostly one monitor and I logged into the screen locker and the screens readjusted themselves correctly. I unplugged the external monitor and the laptop screen when dark. I let it sit for a minute thinking that it would readjust, but it didn't. I plugged in the external monitor again and plasma restarted and the screens readjusted. This monitor is VGA connected to a USB-C adapter that also provides power to the laptop from a USB-C power brick. The KDE bug report would not let me select a report to attach this to.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
