SET_STR_VALUE(values+7, cell->bind_addr[DLG_CALLER_LEG]->sock_str);

Looking at gdb, I see that cell->bind_addr[DLG_CALLER_LEG] == 0 so trying to use it results in the segfault. I have thought about patching that to check for bind_addr being set and bypassing that line if not but I do not think it's the right fix though it probably would avoid the current crash (and do odd things later instead!). I did check that everything else in that function that uses DLG_CALLER_LEG is set correctly and it appears that it is - or at least if not correctly then they are at least set!

The "bogus event 2 in state 5" message is coming out from line 1143 in src/modules/ims_dialog/dlg_hash.c

        case DLG_EVENT_RPL1xx:
            switch (dlg->state) {
                case DLG_STATE_UNCONFIRMED:
                case DLG_STATE_EARLY:
                    dlg->state = DLG_STATE_EARLY;
                    break;
                default:
                    log_next_state_dlg(event, dlg);
            }
            break;

(I didn't really understand why it would set dlg->state = DLG_STATE_EARLY if it's already DLG_STATE_EARLY but...)

I have a couple of core dumps of this from the last day or two - usually seems to crash at least once a week on our pair of kamailio inbound servers. If there's any more info I can provide to help fix this properly rather than my proposed bodge then feel free to ask.
