Bug ID: 444091
Summary: Gwenview segfaults when closing the Tag Editor
Product: gwenview
Version: 21.08.1
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: gwenview-bugs-n...@kde.org
Reporter: r...@ryanplant.net
Target Milestone: ---
Application: gwenview (21.08.1)
Qt Version: 5.15.2
Frameworks Version: 5.86.0
Operating System: Linux 5.13.0-20-generic x86_64
Windowing System: X11
Drkonqi Version: 5.22.5
Distribution: Ubuntu 21.10
-- Information about the crash:
This crash occurs when closing the Tag Editor view, regardless of whether any
tags were added or removed. It happens every time without fail.
Adding and removing tags does work: any changes made in the editor are visible
when you re-launch the application. It only crashes when you close the editor.
It isn't affected by the image file (I tried a dozen, from different sources),
the file permissions, or whether the file is stored in the home folder, a
mounted USB drive, or a network share. The problem persists after resetting
Gwenview to default settings and deleting ~/.config/gwenviewrc.
Other subwindows, like Configure Toolbars and Configure Gwenview, close without
issue.

The crash can be reproduced every time.
