Comment (by rlaager):

 A couple comments from a skimming of the patch...

  1. We don't do the (NULL == some_var) thing.
  2. This is useless, as g_malloc() never returns NULL:
 {{{
 278             read = g_malloc(data->length + 2);
 279     +       g_return_val_if_fail(read != NULL, g_strdup(""));
 }}}
