            Bug ID: 473377
           Summary: Dolphin crashes if you remove a tab after deleting a
                    folder
    Classification: Applications
           Product: dolphin
           Version: 23.04.3
          Platform: Other
                OS: Linux
            Status: REPORTED

Demonstration

If you go to any folder, open it in a new tab, and then delete that folder and
remove the tab, almost any next action with the file system will cause Dolphin
to crash (e.g. if you try to create another folder afterwards, or delete
something)

STEPS TO REPRODUCE
1. Open any folder in a new tab
2. Delete this folder
3. Remove the deleted folder tab
4. Attempt to create any folder, file, or rename.

OBSERVED RESULT
Dolphin is crashing.

EXPECTED RESULT
Nothing's supposed to happen.
