A better fix is: - if (!strncmp(database.format->params.label, "wpapsk", 6) && + if (database.format->params.label && + !strncmp(database.format->params.label, "wpapsk", 6) && But that the segfault didn't occur without --rules indicates that magnum's intended fix do adjust min. length for wpapsk to 8 doesn't always work.
