BTW, the way I figured that out isn't black magic; I just searched
subversion/po/*.po for the error message, which lead me to this code in
libsvn_delta (which implements ^/subversion/trunk/notes/svndiff):

      if (memcmp(buffer, "SVN\0" + db->header_bytes, nheader) == 0)
        db->version = 0;
      else if (memcmp(buffer, "SVN\1" + db->header_bytes, nheader) == 0)
        db->version = 1;
      else
        return svn_error_create(SVN_ERR_SVNDIFF_INVALID_HEADER, NULL,
                                _("Svndiff has invalid header"));
