Package: mutt
Version: 1.5.6-20040907+3
Followup-For: Bug #262272
This crash happens to me every day, probably three times a day. Finally
I got annoyed and built mutt from debian sources, and put gdb on it:

419 subjects = make_subject_list (cur, &date);

421 while (subjects)
422 {
423 hash = hash_string ((unsigned char *) subjects->data,
424 ctx->subj_hash->nelem);
425 for (ptr = ctx->subj_hash->table[hash]; ptr; ptr = ptr->next)

435 (!last ||
436 (option (OPTTHREADRECEIVED) ?
437 (last->message->received < tmp->message->received) :
(gdb) print tmp

Then I went searching through the mutt bug reports and found this one,
so here I am.
Please let me know what else I can do to help. It's obviously a NULL
pointer dereference but I don't know enough about the data structures to
know whether that's the symptom of an even bigger problem. I'm rather
comfortable with gdb, and like I said, get this crash about every three
hours (nine hour work day, three times a day). It always dies with the
status line saying "Sorting mailbox..." and always only for IMAP
mailboxes. I only have one mailbox, period, and it's IMAP (the server is
actually Exchange).
