Bug 429884

Application: konsole (20.08.3)

Qt Version: 5.15.2
Frameworks Version: 5.76.0
Operating System: Linux 5.9.10-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to install new color scheme in Konsole. When I pressed install on a new color scheme it crashed. Happened only once, could not replicate it.

The crash does not seem to be reproducible.

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