Ubiquity Yelp command broken?

When using "yelp" command, ubiquity offers to tag the page with "yelp (restaurant) (near location)" rather than search for the restaurant on yelp. For example, if I type "yelp italian chicago", ubiquity's first option is "tag yelp italian chicago" and the verb "yelp" does not appear anywhere on the list. I'm using Ubiquity 0.5. Sometime I've gotten it to work, but most of the time, no luck. I do have the yelp command installed and it works when I type just "yelp", but after I start typing more than a letters (yelp p) the command switches from yelp to tag.
