Product: gwenview
Version: Other (add details in bug description)
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: gwenview-bugs-n...@kde.org
Reporter: hipsteri...@teletu.it

--> https://bugs.kde.org/attachment.cgi?id=117907&action=edit
a sample of offending file causing the crash.
SUMMARY
Gwenview 16.08.3 crashes when zooming only certain bitmap formats
STEPS TO REPRODUCE
1. open a PC bitmap, Windows 3.x format, 1024 x 1024 x 8
2. zoom picture above 200%
3.
OBSERVED RESULT
Gwenview exits with segmentation fault
EXPECTED RESULT
SOFTWARE/OS VERSIONS
Windows:
MacOS:
Linux/KDE Plasma: Debian GNU/Linux 9.7 (stretch) kernel4.9.0-8-amd64
(available in About System)
KDE Plasma Version: 5.8.6
KDE Frameworks Version: KDE Frameworks 5.28.0
Qt Version: Qt 5.7.1 (compiled with 5.7.1)
ADDITIONAL INFORMATION
attempting to reproduce the crash using the same file PC BMP format but with
different file size and proportions (square 1024x1024) doesn't lead to a
segfault. other bitmaps can zoom up to 1600% flawlessly.
