            Bug ID: 418400
           Summary: Konsole crash when moving a splitted view
           Product: konsole
           Version: 19.12.1
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: yvan.broccard at gmail.com
  Target Milestone: ---

Application: konsole (19.12.1)

Qt Version: 5.13.2
Frameworks Version: 5.67.0
Operating System: Linux 5.5.5-200.fc31.x86_64 x86_64
Distribution: "Fedora release 31 (Thirty One)"

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

I tried to shrink/expand a splitted view of konsole.

Konsole has received recently a new feature, "split view", which is very handy.
I use it a lot. But sometimes when moving the separation line between 2
splitted views makes Konsole crash.

I have seen cases as well where the keyboard shortcuts to switch from one
splitted view to the next do not work anymore (Ctrl+Shift Left, Up, Down or
Right)

The crash can be reproduced sometimes.

-- Backtrace:
