I see.

If we allow it, you will get a suitable error value if it doesn't work.

If a file error occurs, it will do that.  But there are other errors
possible, too (like, out of memory, invalid arguments), so you need a
two-staged error handling

if (err == GPGME_File_Error)
  {
     ... strerror (errno) ...
  }
else if (err)
  {
     ... gpgme_strerror (err) ...
  }

Please be more specific.  It should work, the test case is broken.  We will
change the change we did, though, because the current behaviour is not the
best.  (It's on my TODO list to fix).  But anyway it should work according
to the documented semantics.
 
Thanks,
