Bug 438239

Application: konsole (21.04.1)

Qt Version: 5.15.2
Frameworks Version: 5.82.0
Operating System: Linux 5.12.9-300.fc34.x86_64 x86_64
Windowing System: Wayland
Drkonqi Version: 5.21.5
Distribution: Fedora 34 (KDE Plasma)

-- Information about the crash:
I had just typed CTRL-D to close the konsole.
Then the crash handler protested (I wouldn't have noticed anything amiss if the crash handler hadn't said anything).

This is a knsole with a "new profile" (set as default but KDE doesn't care about the default; well, that's another bug) with:

- Black on light background
- Another font than the hard-to-read "noto"

The reporter is unsure if this crash is reproducible.

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