Bug 465420

Application: konsole (22.12.2)

Qt Version: 5.15.8
Frameworks Version: 5.102.0
Operating System: Linux 6.1.9-arch1-2 x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.26.5 [KCrashBackend]

-- Information about the crash:
Occasionally when I log in to my KDE desktop the login process freezes for a while and I then get a notice that konsole crashed. I always have a konsole running when I shut down the machine, so it is always started automatically on login.

The crash can be reproduced sometimes.

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