I have also come across this problem, although I found my solution. I had to try a few things first. First I realized I had the wrong skeleton and then I found export settings to be incorrect as well. My mesh had no meat caps for dismemberment but the option was selected under the fallout 3 export settings. Removing that solved it.

I had the same problem. Copied and pasted comtypes and now runs beautifully. Thanks to all that know what they are doing and helps out.
