it shows xauth doing this:

unlink("/home/foo/.Xauthority");
link("/home/foo/.Xauthority", "/home/foo/.Xauthority");

which is where it fails.

the code itself clearly can't be responsible for this, it is
using a -c or -n additional postfix on the filename for the
'src' link above, which isn't present.

at least, that appears to be the intent ;)
