Description spryor 2016-12-06 23:52:17 UTC

Application: plasmashell (5.8.4)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.8.11-300.fc25.x86_64 x86_64
Distribution: "Fedora release 25 (Twenty Five)"

-- Information about the crash:
- What I was doing when the application crashed:
Plasmashell pretty reliably crashes whenever a monitor is disconnected or (at least in my setup with Dell P2415Qs) when the monitors power off to go into a sleep mode.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
