release-group searches are returning bad xml.

e.g.: http://musicbrainz.org/ws/1/release-group/?type=xml&limit=100&title=Machine%20Dreams&artist=Little%20Dragon

returns: <?xml version="1.0" encoding="UTF-8" standalone="yes"?><metadata xmlns="http://musicbrainz.org/ns/mmd-1.0#" xmlns:ext="http://musicbrainz.org/ns/ext-1.0#"><release-group-list offset="0" count="1"><release-group type="Album" id="7b1f6301-dbd9-4785-b11b-1175c06b5d9e" ext:score="100" "><title>Machine Dreams</title><artist id="c8a9ae11-63bf-409b-8bf3-a96b3712a2ff"><name>Little Dragon</name><sort-name>Little Dragon</sort-name></artist></release-group></release-group-list></metadata>

note the extra double quotes after ext:score.

what is going on here? is http://musicbrainz.org/ws/1/ a production quality service? i have lost all confidence in musicbrainz and am in the process of migrating my projects away from using it.

this ticket and MBS-2057 are show-stoppers for me. is anyone doing testing before releasing? is the v1 service no longer a priority?
