Hey shrike, why would a brick wall be outside the demarcated safety area? It appears that this was a movable object that was incorrectly parked.......an entirely different situation to taxiing into a fixed object such as a wall or light post. Obviously one tries to avoid this sort of thing at all costs, but **** happens. I'm still interested to know whether the crew were under marshallers orders though, and if the captain was taxiing. If this was the case he would have been shifting his eyes from marshaller to wingtip and back again, not really an ideal situation. On the evidence presented I maintain that the crew were not to blame, but knowing how things work in aviation and particularily in Africa, I have no doubt that they will try to pin it on the crew.
