Thread:Semantic-mediawiki.org:Community portal/Query on specific value of Geographical coordinate type property returns nothing

I'm running Semantic MediaWiki 1.8 on MediaWiki 1.20.2. On my wiki I have pages with the property "Has coordinates" of the type "Geographical coordinate". The values are saved through the use of a template, like this:, using the Maps extension #coordinates parser to give a bit more flexibility when inputing coordinates, while keeping a uniform format on the page. With the Wiki being set up with Norwegian language, #coordinates produces a set of coordinates looking like "62° 41' 46" N, 10° 50' 4" Ø" on the page, which is accepted by the Geographical coordinate type.

When I try to map these pages with Semantic Maps with a query like  (or with regular Maps, for that matter) it works perfect. Queries like  also work perfectly. But if I replace the + with the actual value of one of the pages' "Has coordinates" property, like, the query returns with nothing, even if I copy and paste the value from the query above, and even if I copy and paste the coordinates in the format they were input to the template in the first place.

I'm new to MediaWiki and, of course, all its extensions, so any help would be greatly appreciated. :)

EDIT: I just noticed that if I try to make the above mentioned query without the name-part, as in  the wiki throws the following error on preview and save: "Fatal exception of type MWException"
