           Summary: When renaming fails, Dolphin shows the new filename
                    until refreshed
           Product: dolphin
           Version: 22.07.80
          Platform: Other
                OS: Other

SUMMARY
If you try to rename a file with a very long name, Dolphin shows an error
message saying the rename failed. Nevertheless, the name of the file is still
updated in the view, and the wrong name persists until the view is refreshed.

STEPS TO REPRODUCE
1. Press F2 to rename a file
2. Paste a very long name (e.g. `Paxton, Smolec, Schwab, Gautschy, Bildsten,
Cantiello, Dotter, Farmer, Goldberg, Jermyn, Kanbur, Marchant, Thoul, Townsend,
Wolf, Zhang, Timmes 2019 - Modules for Experiments in Stellar Astrophysics
(MESA): Pulsating Variable Stars, Rotation, Convective Boundaries, and Energy
Conservation.pdf`
3. Press enter
4. Dismiss the error window (that says renaming failed)

OBSERVED RESULTS
Once the error window is dismissed, the file in the view is shown with the new
name (even though rename failed). However, refreshing the view (F5) correctly
shows the file with the old name.

EXPECTED RESULTS
If renaming a file fails, the file should be shown with the old name even
without refreshing the view.
