Wikimedia Bugzilla is closed!

First, I'm not clear at all if this is a bug in Semantic MediaWiki or in Semantic Maps. It could be either.

I'm using the Ask API to retrieve items from a wiki that have coordinates properties attached. The query is

http://roadsignmath.com/w/api.php?action=ask&query=%5B%5BCategory:Signs%5D%5D%5B%5BCoordinates::%2B%5D%5D%7C%3FCoordinates%7Climit=10

This throws an exception:

<?xml version="1.0"?>

I'm using the current master branch off of Git for both Semantic Maps and Maps. I'm using Semantic MediaWiki 1.8 and MediaWiki 1.20.2.

I am able to get around the exception if I pass "%7Cformat=json" along with the query parameter:

http://roadsignmath.com/w/api.php?action=ask&query=%5B%5BCategory:Signs%5D%5D%5B%5BCoordinates::%2B%5D%5D%7C%3FCoordinates%7Climit=10%7Cformat=json
