            Bug ID: 412173
           Summary: crash after system upgrade opening new tab in blank
                    Konsole window
           Product: konsole
           Version: 19.08.0
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: skierpage at gmail.com
  Target Milestone: ---

Application: konsole (19.08.0)

Qt Version: 5.12.4
Frameworks Version: 5.61.0
Operating System: Linux 5.3.0-1.fc31.x86_64 x86_64
Distribution: "Fedora release 31 (Thirty One)"

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

When I ran `sudo dnf system-upgrade reboot` to upgrade to Fedora 31 beta, I had
a Konsole window with three white on black tabs open. When the upgrade
completed and KDE restarted (nice and smooth, well done!), Konsole reappeared
but with a blank white window containing no tabs. I was able to create a new
Konsole window but when I created a new tab in the blank window (I think with
File > New Tab), crash!

- Unusual behavior I noticed:

As above, I've never seen a Konsole window with no shell or tab in it.

-- Backtrace:
