I could reproduce the problem. However, it is different from the
previous one. When you save a file, `set-file-modes' is called by
`basic-save-buffer'. This is needed in order to keep permissions, when
the original file version has been moved to be the backup file.

This operation fails, when you are not the owner of the file. It is the
same for local files: Try to open a local file, owned by root, with
permissions "---xrwxr--". Modify it, and save it.

Maybe modifying `backup-by-copying' helps; I haven't tried.

Best regards, Michael.
