this crash has been around for a while and seems to happen on windows vista systems almost exclusively (>99%) - the signature is responsible for a fifth of all crashes on vista atm.
Note that this is only seen on 6.0.6000 (Vista RTM) which is a vanishingly small fraction of installations. Ideally Vista users should be on SP2 (who knows if it's fixed there or maybe just under a different signature). I don't think we should spend time on this unless someone can provide a repro.
the code in question is just an optimization for >= vista.. it would be easy enough to just make that >= win7 without losing much.

not sure how i came up with the 1/5th of crashes on vista in the first place. not looking that bad...
these stacks all have the autodialer in them and we want to remove that... so depends on that
