Application: krita (4.1.7.101)

Qt Version: 5.11.3
Frameworks Version: 5.53.0
Operating System: Linux 4.19.16-200.fc28.x86_64 x86_64
Distribution: "Fedora release 28 (Twenty Eight)"

-- Information about the crash:
- What I was doing when the application crashed:
Krita booted and functioned as normal until pen was registered as active near the tablet's surface, upon which the programme suddenly terminated. This happens every time I attempted to restart the application.

- Custom settings of the application:
deevad brushes bundle, but there were no issues with it until today. I had installed the pack mid-December 2018.

The crash can be reproduced every time.

-- Backtrace:
Application: Krita (krita), signal: Aborted
