ah, looked at the response, and there was a response code 610.

Which means there was a problem with the API key.
I think previous versions of Maps actually had a popup (may have some from google) that said as much.

would be good if this code provided a more accurate error message.

Subject: Re: [SMW-devel] latest documentation for Maps, SemanticMaps

The usage hasn't changed, but there appears to be something going wrong with the geocoding requests. I don't know why -its only occurring some times -so any help on pinpointing the issue would be appreciated.

Send from my Android phone.
