            Bug ID: 472507
           Summary: Kate crashes when attempting to move "Diagnostics"
                    button from 'Bottom of the Screen' to 'Right Side of
                    the Screen'
    Classification: Applications
           Product: kate
           Version: 23.04.2
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kwrite-bugs-n...@kde.org
          Reporter: rxsi...@tutanota.com
  Target Milestone: ---

Application: kate (23.04.2)

Qt Version: 5.15.10
Frameworks Version: 5.108.0
Operating System: Linux 6.3.12-200.fc38.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 38 (Workstation Edition)
DrKonqi: 5.27.6 [KCrashBackend]

-- Information about the crash:
Whenever I "right-click" on the "Diagnostics" button and select the "Right
Side" option, Kate crashes.
However :
*  1  *   I have NOT tried any other option.  Only the "Right Side" one.
*  2  *   I can move the "Output" button to the "Right Side" of the screen by
right-clicking on the button.  So, the "Output" button does NOT trigger any
unusual behaviour.
*  3  *   I recently upgraded this system from Fedora 36 to Fedora 38 ( two,
maybe three days ago )
*  4  *   After the upgrade, the system showed problems.  Some pretty severe. 
I tracked those to Virtual Box 6.1.  Upgraded to Virtual Box 7.0 and things
improved a lot, but not 
every bug went away.
*  5  *   Finally, I removed Virtual Box for good.  I haven't seen any problems
yet, but, that was yesterday.  So, still testing how it goes.

The crash can be reproduced every time.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
