Bug 504893

Application: kate (22.12.3)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-37-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux 12 (bookworm)
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
I needed to quickly diff two files and thought I'd try Kate for once since it's installed;
I opened Kate, pressed CTRL + N twice to get two documents, and pressed CTRL + SHIFT + L to split the view.
I then went to close the second document in the left split and pressed Middle Mouse Down on it, which caused the crash.

After re-opening Kate and going through the exact same steps, it did NOT crash a second time...

The crash does not seem to be reproducible.

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