Description Amichai Rothman 2016-06-26 10:25:03 UTC 
Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-24-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- Unusual behavior I noticed:

When leaving the computer for a while and returning, instead of the monitors being suspended, they are on and this plasma crash dialog appears, often several of them.

The crash can be reproduced every time.

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