Ok, thanks. I've dug a little further, and it seems like the problem is that a column of all missing values ends up as a column of all None's. When you create a (masked) array from a list of None's, you end up with an object array. On one hand I'd love for things to behave differently in this case, but on the other I understand why things work this way.
Ryan, Mind giving r6434 a try? As usual, don't hesitate to report any problem.
Works great! Thanks for the quick fix. I had racked my brain on how to go about fixing this cleanly, but this is far simpler than what I would have done. It makes sense, since all I really needed for the masked column was something *other* than object.
