It is caused by your Google Maps. I have the same problem and I don't know how to solve it. Somehow Google Crawls your page and hits the Google Maps error message "Sorry we have no imagery here"
peterdebruij is correct (BTW, Welcome to WebmasterWorld!).
One of sites I am looking after has the same problem, with keywords that make up the above phrase being shown in all languages the site uses.
This is likely to happen if there are many pages on the site that each show their own Google map.
I am wondering whether limiting the zoom to the level so that map image always exist would get rid of these "keywords" but have not tried this yet.
