Description Greg Lepore 2015-09-03 17:20:15 UTC

Application: gwenview (15.08.0)

Qt Version: 5.4.2
Operating System: Linux 4.1.0-3-generic i686
Distribution: Ubuntu Wily Werewolf (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

Just upgraded to Kubuntu Wily Beta 1 and I get a crash 100% of the time in Gwenview when I click the 100% zoom button which I have in the status bar. My default is set to Fit.

The crash can be reproduced every time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault

Comment 1 Greg Lepore 2015-09-03 17:23:07 UTC

Note that the problem does not occur when manually clicking the Plus symbol to get to 100% zoom. But the problem did occur once when using the menu commands to zoom an image. Problem does not occur on all images or 100% of the time (although it was when I reported the bug.)

Comment 2 Greg Lepore 2015-10-03 15:24:02 UTC

Purging Gwenview and deleting all associated rc files and any file with Gwenview in the name, and then re-installing the program appears to fix the problem.

Comment 3 Greg Lepore 2015-10-03 20:29:35 UTC

Correction to previous post, deleting everything fixes the problem, temporarily. The problem has now returned. Definitely seems to be related to settings, or configuration of toolbars (which I always change and re-arrange after a fresh install.)

Comment 4 Greg Lepore 2016-01-20 12:26:33 UTC

Bug is still occurring on:

Version 15.08.3
KDE Frameworks 5.18.0
Qt 5.5.1 (built against 5.5.1)
The xcb windowing system

I am willing to debug whatever is necessary to fix this bug, it is really messing up my ability to get work down with Gwenview.

Comment 5 Christoph Feck 2016-05-11 00:09:14 UTC

It looks related to LCMS2 library.
