I can reproduce this with gui-gtk as well.  The problem is in the core
client or server - somehow the client thinks there is a single unit in
the city, but the pointer for that unit has some bogus data.  Valgrind
may be useful here, but I can't run it right now.  I don't know where
this bogus data comes from.

(gdb) p *punit
$2 = {type = 1078749696, id = 220, owner = 0, x = 47, y = 46, veteran =
false, 
  homecity = 13, moves_left = 0, hp = 20, unhappiness = 0, upkeep = 1, 
  upkeep_food = 0, upkeep_gold = 0, foul = 1056964608, fuel = 0, 
  bribe_cost = 137056632, ai = {control = false, ai_role = 137056608, 
    ferryboat = 0, passenger = 131176, bodyguard = 0, charge = 0}, 
  activity = ACTIVITY_FORTIFYING, goto_dest_x = 0, goto_dest_y = 0, 
  activity_count = 0, activity_target = S_NO_SPECIAL, focus_status = 112, 
  ord_map = 137127224, ord_city = 66089, moved = false, paradropped =
false, 
  connecting = false, transported_by = 0, pgr = 0x0}
