Looks like a specific offset doesn't work on api/issues?

So I came accross an address in my attempts to test this api, and this url returns blank.

http://www.comicvine.com/api/issues/?api_key=XXXXX&offset=217400

217300 and 217500 both work, so I'm guessing something along the lines of an issue in this resultset is corrupt and does not allow the api to draw it's data in a proper xml format?

Seems like these two out of the 100 have issues:

http://www.comicvine.com/api/issues/?api_key=XXXXX&offset=217434&limit=1

http://www.comicvine.com/api/issues/?api_key=XXXXX&offset=217435&limit=1
