Seems to work fine for me with 1.2.4 (well, 1.2 branch tip):

tpm at xps:~/gst/1.2/code$ ./read_tags
file:///home/tpm/samples/misc/729751-04-Berceusepourlesméchantsenfants.opus

             audio-codec : Opus

It's also not a "crash", but it errors out after receiving a GST_MESSAGE_ERROR
on the pipeline bus. It would be good to know what the error is. Either run the
code with GST_DEBUG=*:INFO or modify it like this:

  if (GST_MESSAGE_TYPE (msg) == GST_MESSAGE_ERROR) {
    GError *err = NULL;
    gchar *dbg = NULL;

    gst_message_parse_error (msg, &err, &dbg);
    g_printerr ("ERROR: %s\nDebug: %s\n", err->message, dbg);
    g_error_free (err);
    g_free (dbg);
    return 1;
  }

Maybe you just don't have some required plugin installed. Does  gst-inspect-1.0
opusdec  work (show stuff)?
