Bug 375325

Application: krita (3.1.88 (git d87034e))
 (Compiled from sources)
Qt Version: 5.7.1
Frameworks Version: 5.30.0
Operating System: Linux 4.8.13-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I had a group layer with two layers with some brush strokes.
I selected the group and then went to layer menu > Import/Export > Save Group Layers

A dialog popped up, i chose the location for the save and selected png as the resulting format (I think it was exr by default)

the moment I clicked "ok" krita crashed and triggered Dr. konqi

Below is the Backtrace from Konqi

The crash can be reproduced every time.

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