Follow-up Comment #3:

Attached pathc makes homeless caravans to seek new homecity before even
considering traderoutes. Caravan that is going to help in wonder building does
not need homecity, so looking for one would just waste its turns.

Follow-up Comment #2:

While this particular crash was in the code in TRUNK only, there's more places
where caravan without homecity crashes. I managed to setup crash in
caravan_find_best_destination() ->
caravan_find_best_destination_withtransit(src == NULL) which means that S2_4
at least is affected. Code has changed quite a much since S2_3 but I cannot
see how the old code could survive with homeless caravan. NULL gets stored to
caravan_result -structure and is happily used from there.
