I have had also the problem of the game crashing when entering the docks (exactly at the doorframe entering it.)
The problem "fixed" itself: after finishing the turian arc quest.
May working theory is, that the script about those arc visitors (asari and salarians) at the immigration desk is the root cause.
When finishing the turian arc quest, there are turians at the desk.
Maybe the script works properly thereafter.
I only got a cutscene with the Asari ark rescue, when I got Salarians no cutscene no salarians either at the desk.
