Application: dolphin (19.04.2)

Qt Version: 5.12.3
Frameworks Version: 5.59.0
Operating System: Linux 4.15.0-52-generic x86_64
Distribution: KDE neon User Edition 5.16

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

Right clicked on a file and chose "open with kwrite". The file opened but dolphin crashed.. Looks to be related to wayland.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
