OS: Linux (Fedora 43 KDE) 64bit
==================================
Short description of the problem
==================================
Folders cannot be deleted, does not matter if it is empty or not.
When trying to delete a folder the confirmation box appears, but after clicking "Yes" the folder is not deleted.
Files, however can be deleted, this only happens with folders.
==================================
Further infos and things I tried
==================================
Permissions should not be an issue as a new test-folder in my home-folder has the same problem.
Delete is working in Dolphin and also using another appimage "Double commander".
I already removed the xnview.ini and tried different versions of XNView MP back to 1.4.5, all show this behavior.
The problem occurred at around January/February 2026, where I probably installed Fedora updates.
I set up a new virtual Fedora 43 and tried XNViewMP there, it shows the same behavior.
So it seems to be broken even in a new installation of Fedora 43.
==================================
Effect: Deletion of folder is not possible
==================================
To reproduce:
1. Select Folder to be deleted
2. Right-Click and Delete OR Press "Del" on keyboard
3. Confirm the deletion of the folder in the message prompt
4. Folder is not deleted
Actual behavior (bug): Folder is not deleted
Expected behavior: Folder should be deleted
