Normally we deal with NULL printf arguments like this (assuming the uri
argument is the only NULL argument to be concerned about, the other
arguments can use the same technique if needed):

         g_print ("totem_embedded_set_uri uri %s base %s => resolved %s\n",
         uri ? uri : "(null)",
         base_uri,
         emb->current_uri);
