I had this problem several times on the teetering wrecked ship as well - I think it's called the MSV Estavenico? - in a difference place each time. Eventually I resorted to walking veeeeery carefully and not going near any walls or edges.
I've also just had it happen on the airlock security console on the Strontium Mule, just after you walk out of the cargo bay. It's fairly easy to reproduce, too - walk into the left front corner or left side of the keyboard while facing towards the cargo bay and slightly to the right (like, if directly perpendicular to the console monitor is north, you want to be facing roughly NNE). I've managed to reproduce it three times in as many minutes doing this.
EDIT: Huh, managed to get Shepard back on the ground after walking onto the security console. That wasn't possible on the Estavanico - he would literally stand on thin air. I couldn't manage to get off the keyboard the first two times, either, so it's still a bit of a problem.
Oh, and this is the PC version of ME2, just in case that wasn't clear.
