            Bug ID: 422555
           Summary: Crash when tagging images in kphotoalbum
           Product: kphotoalbum
           Version: 5.6.1
          Platform: unspecified
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kpab...@willden.org
          Reporter: aseq...@gmail.com
  Target Milestone: ---

Application: kphotoalbum (5.6.1)

Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: Linux 5.3.0-53-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18

-- Information about the crash:
- What I was doing when the application crashed:
I was tagging multiple pictures in kophotoalbum, I can consistently trigger the
bug. I've been tagging pictures before without the same issue, but I can
consistently reproduce it now.

The crash can be reproduced every time.

-- Backtrace:
Application: KPhotoAlbum (kphotoalbum), signal: Segmentation fault
