PM does show right profile - I always have {icc} variable in my Info text.
I tried different combination of options while extracting JPEG previews selecting/deselecting "Embed ICC Profile" option.
D3 firmware is: A 2.00, B 2.00. It is not a preproduction unit.
These NEFs are straight from the camera. No software was used to ingest, just drag'n'drop from card to desktop/folder.
Toggling 'c' key or using the button in the toolbar change nothing, while if the NEF is tagged by D3 as sRGB 'c' key or the button works as expected - turning on and off colour management.
I have no issues with the same NEF files from the same D3 tagged with AdobeRGB if I open them on my Mac (OS X 10.5.6, PM 4.5.4) or on another computer (Vista Premium w/o SP1, PM 4.5.3.1).
This post describes similar behaviour,but with Canon camera:
