I cannot reproduce this here.  Can you show a reproducible recipe
starting from "emacs -Q"?

Does this happen for any 2 buffers, or just for some?

When this happens, what do you see in the buffer *ediff-diff*?

The file names you show above are identical.  Is this a typo, or do
you indeed compare a file to itself?
