Bug ID: 381364
Summary: "Gwenview crashes when going in Full Screen mode with
Grayscale JPEG images"
Product: gwenview
Version: unspecified
Platform: Debian stable
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: gwenview-bugs-n...@kde.org
Reporter: davidebeatr...@gmail.com
CC: myr...@kde.org
Target Milestone: ---
Application: gwenview (16.08.3)
Qt Version: 5.7.1
Frameworks Version: 5.28.0
Operating System: Linux 4.9.0-3-amd64 x86_64
Distribution: Debian GNU/Linux 9.0 (stretch)
-- Information about the crash:
- What I was doing when the application crashed:
I have a set of JPEG images, all coming from the same source.
Gwenview works fine with the TrueColor images, but it crashes as soon as I
click on the Full Screen button with a Grayscale one. The program goes in Full
Screen mode, but the image is not correctly zoomed, as it's blurred, and then
it immediately crashes.
A few times it worked correctly, when I left the image open for some time.
While writing this report I noticed that Gwenview also crashes when moving the
zoom slider fast.
The crash can be reproduced every time.
-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
