            Bug ID: 412402
           Summary: Kmail crashes when enabling/disabling favourites
                    folders in kmail settings
           Product: kmail2
           Version: 5.12.1
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: james at thornber.io
  Target Milestone: ---

Application: kmail (5.12.1)

Qt Version: 5.13.1
Frameworks Version: 5.62.0
Operating System: Linux 5.2.14-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

I was disabling the "Show favourite folders view" after disabling then Kmai
crashed.  Likewise if I go back and then enable it, then Kmail crashes again.
So it seems to occur if I toggle between these two options.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
