Frameworks Version: 5.50.0
Operating System: Linux 4.18.0-11-generic x86_64
Distribution: Ubuntu 18.10

-- Information about the crash:
- What I was doing when the application crashed: I had restarted after the distro upgrade and just wanted to check some files. Every time I try to open dolphin, it crashes. Don't know what to do next!!

The crash can be reproduced every time.
