I had this problem too, which turned out to be quite interesting: the combination of attachment_fu with Ruby 1.9.2 and Passenger 3 is not a good one.
If your app runs on WEBrick (mine did) you can fix this by patching attachment_fu. In any case my fix might help you, because it was in a monkeypatch to Tempfile.
