Description kkolle 2016-12-21 18:38:59 UTC
Application: plasmashell (5.8.4)

Qt Version: 5.6.2
Frameworks Version: 5.27.0
Operating System: Linux 4.8.14-200.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

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

In the lates versions of KDE the taskbar get on the laptop screen, so until the latest update I could move it back to the main screen by changing the configuration from VGA to Laptop - apply and back again.

Now after the update I got yesterday this doesn't work any more, so I tried to shut off the laptop screen and back on. This solved the problem - probably after the crash.

The screen background also cannot keep the settings (Desktop with slidshow) from login to login.

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