Sentry Crash Report:

Description Andreas Hartmetz 2018-03-20 13:06:28 UTC 
Application: plasmashell (5.12.80)
 (Compiled from sources)
Qt Version: 5.11.0
Frameworks Version: 5.45.0
Operating System: Linux 4.13.0-37-generic x86_64
Distribution: Ubuntu 17.10

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

Log in

- Unusual behavior I noticed:

The wallpaper (background) appeared, then with a slight delay the taskbar appeared, with several entries drawn on top of each other only slightly horizontally displaced. Then the shell froze and crashed. Then it restarted and kept working normally after that. It happened on two out of two logins after switching to Qt 5.11 (debug builds by the way, hence the assertions!) so I'm not sure if it happens every time.

I guess this looks quite like an upstream bug really...

The crash can be reproduced sometimes.

-- Backtrace:
