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.
