Sorry, no, it isn't.  When you report this problem to the bug tracker,
please make sure the description answers the following questions:

  . what do you mean by "binary buffer" (or "text buffer")?
  . I didn't say that gpg's output is the problem, I asked whether
    it's human-readable text or byte stream in this case.  I
    understand it's text (the gpg version number), in which case I
    don't understand why the code sets coding-system-for-read to
    'binary' -- it sounds like a mistake.  Can you show the place
    where this is done?
  . you are assuming that using nil for coding-system-for-read is
    correct, but I don't think it is, so if you can show where that is
    done, it might be the beginning of the solution.
