Sentry Crash Report:

Description wolthera 2017-08-23 22:47:13 UTC

Application: krita (4.0.0-pre-alpha (git 6c4ddbd))

Qt Version: 5.9.1
Frameworks Version: 5.37.0
Operating System: Linux 4.10.0-32-generic x86_64
Distribution: KDE neon User Edition 5.10

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

I was trying to run gmic on a picture, then changed input from active to active and bellow, and then this crash happened.

Note: I am running gmic from the standalone because I am building from source.

Note2: It's past midnight so this might not be too lucid.

-- Backtrace:
Application: Krita (krita), signal: Segmentation fault
