Application: plasmashell (5.6.3)

Qt Version: 5.6.0
Frameworks Version: 5.21.0
Operating System: Linux 4.5.2-302.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

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

Absolutely nothing. What I have found is that plasmashell will crash whenever the computer is left alone for an extended period of time. No idea what the length of time is (sorry, not watching the clock :) ). Sometimes the screen is locked - when the screen is locked it doesn't matter whether it's the built-in (KDE) or another screen locker (XScreenSaver) program is used.

The crash can be reproduced sometimes.

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