Description
If a case-sensitive filesystem is mounted case-insensitive (the default) via NFS on Windows, QFile::rename() will delete the source if the path matches the destination (case-insensitively).
This is a problem, since the most common way to mount NFS exports (typically from Linux) is case-insensitively since it is more compatible with Windows applications, for example.
mount -o anon \\192.168.0.1\mnt\share Z:
Windows Explorer refuses to do such renames, instead we get a dialog: "Rename file: The source and destination file names are the same". Which implies it is possible to detect this condition in Qt.
To work around the problem, we can mount case-sensitive:
mount -o anon casesensitive=yes \\192.168.0.1\mnt\share Z:
