Bug 399990

Application: kate (18.08.2)

Qt Version: 5.12.0
Frameworks Version: 5.51.0
Operating System: Linux 4.18.14-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
open dolphin
open some text file with kate (kate shows up)
minimize kate, open another text file (kate does NOT show up)
close kate... plasma shows crash notification

The crash can be reproduced every time.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
