Thanks. Apparently the comment before line 11595 in packet-smb.c is wrong.

                        case TRANSACTION_MAILSLOT:
                                /* This one should be safe to call
                                   even if s_tvb and sp_tvb is NULL
                                */
                                if(d_tvb){
                                        dissected_trans = dissect_mailslot_smb(
                                                sp_tvb, s_tvb, d_tvb, NULL, pinfo,
                                                top_tree);
                                }
