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.
