This warning probably appears because the above file path (to the diff) is (in a directory that somewhere is) a symbolic link, and is harmless if that is the case.

I haven't noticed this with earlier versions (nor in other Qt-based applications), and it may be related to why QFileSystemWatcher prints a warning.
