            Bug ID: 423759
           Summary: Opening folder properties crashes Kontact
           Product: kontact
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs@kde.org
          Reporter: t...@tsbarnes.com
  Target Milestone: ---

Application: kontact (5.13.3 (19.12.3))

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-40-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I was attempting to open the folder properties on a Gmail account folder. It
doesn't crash every time I do it, but about half the time. The same Gmail
account also performs much worse than my other accounts.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
