SUMMARY
When I edit a .desktop file properties, e.g. to change the icon, instead of changing the original file it creates a new one, stripping the first character of the file name (so e.g. kate.desktop becomes ate.desktop).

STEPS TO REPRODUCE
1. In Dolphin, go to ~/.local/share/applications/
2. Open properties of any .desktop file there
3. Change anything, e.g. its icon, display name, etc.
4. Click OK

OBSERVED RESULT
A new .desktop file appears, with the first character stripped from the name (e.g. if you edited kate.desktop, the new file is named ate.desktop).

EXPECTED RESULT
The original file is edited/replaced.

ADDITIONAL INFORMATION
If you edit file permissions instead of other properties, it tries to change them on the wrongly-named file, fails with an error message, and then creates that file anyway.

The same happen if you edit an application entry from the launch menu IF the corresponding .desktop file is in .local/share/applications/ already; otherwise the new file is created there with the correct name.

Editing .desktop files in other locations is NOT affected.

Editing through kmenuedit is not affected but, it doesn’t show the very file I needed to edit, userapp-Firefox-<...>.desktop.
