At the moment our server don't like multiple <locationquery> elements in 
an <iq>. There is no particularly good reason for this and I will fix it.

Something wrong was probably not right there (!) Possibly to do with the 
above.

It will publish as much info as can be derived from your references. We 
do have a rudimentary cell to lat/lon database, and if a match is found 
it wil use this to derive your coordinates. If not it will default to 
the center of your country (derived from MCC) associated with a huuuuge 
error. From lat/lon it will try to obtain region, city and area names 
(with a little help from geonames.org).

Note that the publish will most likely fail, since your host server will 
propably let our server publish to your PEP node on your behalf. Some 
configuration might be needed for this to work I believe.

This is probably related to your error above. Some how no results could 
be found (even so it suggest an error for your location had it been 
found. Er...  right)
