            Bug ID: 420820
           Summary: Konsole 20.04.0 crashes on start
           Product: konsole
           Version: 20.04.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: michael at michaelmarley.com
  Target Milestone: ---

Application: konsole (20.04.0)

Qt Version: 5.12.8
Frameworks Version: 5.69.0
Operating System: Linux 5.7.0-050700rc3-lowlatency x86_64
Windowing system: X11
Distribution: Ubuntu Groovy Gorilla (development branch)

-- Information about the crash:
Konsole 20.04.0 crashes every time I try to start it.  I tried deleting the
configuration file but that had no effect.  Reverting back to 19.12.x stops the
crashing.

I'm using the packages from
https://launchpad.net/~kubuntu-ppa/+archive/ubuntu/staging-frameworks.

The crash can be reproduced every time.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
