            Bug ID: 378134
           Summary: Crash on exit of document (mostly after exporting)
           Product: krita
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: krita-bugs-n...@kde.org
          Reporter: raghavendr.ra...@gmail.com
  Target Milestone: ---

Application: krita (3.1.88 (git cb56566))
 (Compiled from sources)
Qt Version: 5.8.0
Frameworks Version: 5.32.0
Operating System: Linux 4.10.5-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Krita crashed after I exported a png to jpg and closed the document.
I have seen this random crash on document close at other times too. But if my
observation is correct it happens mostly after doing export and close. I may be
wrong in this assumption though.

The crash can be reproduced every time.

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