You can do it this way, but you can do it a way more
resembling your original description too.  I don't know what
your intended error reporting interface for other I/O errors
looks like, but if it can be querried after the fact, i.e.
it maintains something like errno, then

  buf = g_object_new(X_TYPE_FILE_BUFFER, "filename", "foo.txt", NULL);
  if (!buf) {

can be done completely equivalently

  buf = g_object_new(X_TYPE_FILE_BUFFER, "filename", "foo.txt", NULL);
  if (x_file_buffer_error(buf)) {

If not, the x_file_buffer_load_from_file() approach with
immediate error reporting makes more sense.

Thanks, I'll keep both ideas in mind. Although for this case the
GError based one will make more sense.

Thanks again,
Alexandre Moreira.
