Description wolthera 2018-02-12 18:24:25 UTC

Application: krita (4.0.0-beta1 (git 0c60008))

Qt Version: 5.9.3
Frameworks Version: 5.42.0
Operating System: Linux 4.13.0-32-generic x86_64
Distribution: KDE neon User Edition 5.12

-- Information about the crash:
I only managed to get this document because there seems to be a certain bug with the way how Krita reports the DPI to python and back.

None the less, scaling the document in question to 72 DPI consistently crashes Krita and gives the following backtrace.

The crash can be reproduced every time.

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

Comment 1 wolthera 2018-02-12 18:26:27 UTC

Created attachment 110571 [details]
Document that crashes Krita when scaled to 72 dpi.

Mind you, it's proly some division by 0 kind of error.

Comment 2 Halla Rempt 2018-02-15 11:24:50 UTC

I don't get a crash... What are the exact settings for the scale image dialog?

Comment 3 Halla Rempt 2018-02-26 15:14:42 UTC

It must be yet another timing issue. The crash occurs after the image has been scaled, when the vector layer starts repainting:

#8  0x00007f80b3efd207 in KisShapeLayerCanvas::slotStartAsyncRepaint (this=0x11a10dc0) at /home/wolthe

Can you still reproduce this crash with that document?
