Description Aron Heinecke 2017-02-15 11:27:56 UTC 
Application: systemsettings5 (5.8.5)

Qt Version: 5.6.1
Frameworks Version: 5.28.0
Operating System: Linux 4.7.4-040704-generic x86_64
Distribution: Ubuntu 16.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
The Crash happened after Selecting "Desktop Effects" in the System Settings and also for Selecting Workspace Theme.

- Unusual behavior I noticed:
Under "Desktop Behavior" the crash only occurs for "Desktop Effects", selecting the "Workspace Theme" Menu directly crashes the application.

- Custom settings of the application:
My Login Loading-Screen is disabled as of the KDE Bug that it doesn't disappear for 20 Seconds (even though everything's loaded).

As a side note: This hasn't happened with the non-backport version of 16.04 LTS. This is a little bit disappointing.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

So, after doing another reboot everything seems to work again.
I don't know what exactly caused this.
- upgraded to backports
- reboot
- tried if the driver manager would be working now
- installed new nvidia driver (I'm using my intel HD GPU during this whole time)
- ( no reboot!? )

And now are the crashes incoming:
- Launcher for one application vanished, regardless of setting "show launcher" on/off
- Logout/Reboot/Shutdown Screen-Crash as reported in #374665
- System Settings crashing as reported in #376513
- Lock-Screen broken

After another reboot everything is back to normal.
