Only the Votes entity set has this problem.

e.g. https://data.stackexchange.com/stackoverflow/atom/Votes

  • Surprised nobody had reported this error just because it was not stopping any functionality from working (I assume). This error has been there from atleast past 2-3 weeks Feb 21, 2011 at 6:38
  • So will it be fixed? Feb 27, 2011 at 21:19
  • April 3rd, and still broken... Apr 3, 2011 at 15:34
  • somebody needs to take ownership of the odata piece, we see very little value investing time there as our api is tons more useful

Votes and VoteTypes, actually. As waffles mentioned, consuming the API seems much more useful and sane than using odata, but since this was easy enough to address I fixed it anyway (pending pull and deploy).
