Application: yakuake (3.0.5+)

Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: Linux 4.15.0-101-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18

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

I had an SSH session open in a tab (which was probably stale to an internet change)
that tab was marked as "do not close" and "keyboard input disabled"

I deactivated those flags and tried to write into the tab, whole yakuake crashed.

-- Backtrace:
Application: Yakuake (yakuake), signal: Segmentation fault
