Bug 386890

Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.10.0-37-generic x86_64
Distribution: Ubuntu 16.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I'd just finished running Nvidia's driver installer. When logging into Plasma, I immediately got a black screen and the bug tracker came up.
- Custom settings of the application:
I had allowed the install script to change the X configuration.

The crash can be reproduced every time.

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