OK, I found a very easy way to reproduce the bug:

With the *scratch* buffer do a M-x message-mode, and then type one 
character to change the buffer. Then do C-x C-c. Emacs asks whether to 
save the buffer. If you say 'y', you have the problem. OK, I skipped 
the "emacs -q", but that shouldn't matter much (I hope).

Honestly the real problem is that parent directories do not exist, 
because when trying to save *a*, the error is "invalid argument".

Now is that still a bug or not?
