It seems most (all?) of the posts on this topic revolve around an aircraft contacting the airbridge which was in the wrong place during the final few yards of the taxi.
How about considering that perhaps everything was in order, airbridges clear etc and then an over-enthusiastic airbridge driver began moving the airbridge into position prematurely, ie before the aircraft had come to its final position?
There's any number of possible scenarios. There was the classic where a certain Middle Eastern airline was taxiing to the stand equipped with (I think) AGNIS/PAPA and the PF looked away / was distracted when the moving indicator on the PAPA was approaching the stop point but was slowing to a stop. While he was otherwise engaged the aircraft actually did stop, but past the stop point. He looked back up, and noticing the gap between the marker for the aircraft (memory fails me - I think it was a 777) gave it some welly to line it up, assuming he hadn't gone far enough whereas in reality he had gone through the stop point. Did quite a bit of damage as I recall.
