I highly believe it was a mistake on their end, the way it appears, with no cache either, which would explain what would happen if someone on their end edited it manually and left a space in the url. The url may be stuck in their database, and as it recrawls each month it doesn't crawl the title or description, because it doesn't resolve, for some strange reason is now stuck in their system.

I presume someone manually typed it in wrong with the space on their end by accident.

I know for darn sure that it wasn't on our end. Just imagining the thoughts that this could be possible should be frightening to any online business certainly a wakeup call.

Bigdave your theory doesn't make sense to me. The urls would point to a domain at least I feel. The way the www.%20domain.com is ... I could see it being domain.com/index%20.html or something but not within the domain name itself.
Bigdave I would be delighted to see even 1 you can find out of 8,058,044,651 listings.
