Description Matěj Laitl 2016-01-04 22:36:14 UTC 
Application: gwenview (15.08.3)

Qt Version: 5.5.1
Operating System: Linux 4.0.5-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
To reproduce:
1. Open gwenview with a jpeg image (will attach)
2. Immediately click the "100 %" zoom button, or use middle mouse button to do the same
3. Crash.

Gwenview does *not* crash when I first use the zoom slider (which itself works fine), and then use to "toggle 100% view" functionality afterwards.

This crash does *not* happen on all images, but happens every time on 2 of 3 images from one scanning batch that I'll attach.

The crash can be reproduced every time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

I can reproduce the crash on Debian Unstable.

Just happens with some larger pictures.

Comment 18 Christoph Feck 2016-10-14 04:01:10 UTC 
It seems to happen on grayscale images. Probably the code that passes the image data to the LCMS library does not correctly handle QImage::Format_Grayscale8.

Did anybody see this bug also with color images?
Comment 19 Christoph Feck 2016-10-14 04:55:01 UTC 
This could fix it. Feedback appreciated.

I get the crash on full color images, I've never tried grayscale images. I get the crash on almost 100% percent of images.

Comment 22 Christoph Feck 2016-11-15 10:21:26 UTC 
The only other idea I have is that it happens when switching between images without alpha channel (RGB, mostly JPEG) and images with alpha channel (RGBA, usually PNG).

Git commit 8f6d726fce8fae49991d8f4c9062cbedba70e58a by Christoph Feck.
Committed on 06/12/2016 at 15:22.
Pushed by cfeck into branch 'Applications/16.12'.

Fix crash when updating the scaler

The color correction transform needs to be updated even if it
was already created, because a change in image depth or format
may require an updated transform.
