Application: konsole (20.12.2)

Qt Version: 5.15.2
Frameworks Version: 5.79.0
Operating System: Linux 5.4.0-65-generic x86_64
Windowing System: X11
Drkonqi Version: 5.21.0
Distribution: KDE neon User Edition 5.21

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

Exited Konsole via Ctrl+d. This crash only seems to happen when a Konsole window has been open for a while (> 10 minutes?). Since the "crash" is only reported by the KDE crash helper when already exiting the application, this isn't a huge deal as it doesn't result in data loss or anything.

- Custom settings of the application:

I have the Konsole window set to "Fullscreen: Apply Initially" via a Window Rule in KDE Settings. Other than that, there's really nothing special/unique about my Konsole setup.

The crash can be reproduced sometimes.

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