Sentry Crash Report:

Description Raghavendra kamath 2017-03-27 04:22:29 UTC 
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
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Comment 1 Raghavendra kamath 2017-03-27 06:35:48 UTC 
I forgot to mention an important information. I am using the svg/loading branch and this happens in that branch.
Comment 2 Dmitry Kazakov 2017-04-10 11:48:04 UTC 
I couldn't yet reproduce the crash, but after exporting, there is some leak of the tiles reported

Timing issues on closing krita can lead to the display
renderer being gone before the palette docker is closed,
which is why we put the pointer in a QPointer.
