Bug 457105

Application: kate (22.04.1)

Qt Version: 5.15.3
Frameworks Version: 5.96.0
Operating System: Linux 5.18.13-200.fc36.x86_64 x86_64
Windowing System: X11
Distribution: "Fedora release 36 (Thirty Six)"
DrKonqi: 5.25.3 [KCrashBackend]

-- Information about the crash:
Installed Kate, opened it, clicked on Filesystem on the side bar, and it crashed. This is consistent.

I uninstalled Kate Plugins (thus removing Filesystem, Git, Projects and Documents from the sidebar) and the crashing stopped. Obviously something about the plugins needs to be fixed.

The crash can be reproduced every time.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
