Comment 10 for bug 1553040

Unfortunately the stack trace isn't particularly useful. If you can reproduce this, it would be helpful if you could install systemd-dbg and look at the generated stack trace then?

This crashes in:

bool logind_wall_tty_filter(const char *tty, void *userdata) {

        Manager *m = userdata;

        assert(m);

        if (!startswith(tty, "/dev/"))
                return true;

        return !streq(tty + 5, m->scheduled_shutdown_tty);
}

startswith() does a strlen() and a strncmp(), so I don't think it's that as it would already segfault in strlen(). m is also not NULL (due to the assert), so I figure it's the m->scheduled_shutdown_tty that is NULL.

I'll dig through the code to see where this is being set.
