Sentry Crash Report:

Description Andrew Shark 2024-04-18 14:23:04 UTC 
STEPS TO REPRODUCE
1. Create two files in home directory: 1.txt and 2.txt
2. Open 1.txt in Kate, Open 2.txt in Kate.
3. Click View | Split View | Split Vertical
4. Close 2.txt in the left view.
So now you have the only tab in left view which is 1.txt, and the only tab in right view with 2.txt.
5. In the right view, right click on the 2.txt tab, and choose "Delete".
6. It asks "Do you really want to delete...?", answer Yes.

OBSERVED RESULT
Kate crashes

EXPECTED RESULT
Kate should not crash. As there are no more tabs opened in right split view, it should be either closed, or a placeholder should be shown there.
