Bug 465885

Application: konsole (22.08.2)

Qt Version: 5.15.6
Frameworks Version: 5.98.0
Operating System: Linux 5.19.0-31-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.10
DrKonqi: 5.25.5 [KCrashBackend]

-- Information about the crash:
I was testing out ChatGPT, and I asked it to write a quine in Python. The text it produced was "s='s=%r;print(s%%s)';print(s%s)", which I then tried to copy into the Python REPL. When I did this, it crashed Konsole. This happened everytime I copied the text into the terminal when it was running Python, but did not happen when it was pasted into the terminal normally.

The crash can be reproduced every time.

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