Here's my TDO-Mini-Form:
At the bottom users can submit a location for their post. It works fine if you pinpoint an exact location, but if you search in the 'Find Location' bar, it will return the results, but when one is selected and the form is submitted, it says 'GeoMashup reported an error when attempting to process location'
I also have an upload image feature. If an image is uploaded, and then you experience this error, the upload is wiped off, with the user probably unaware of this when trying to relocate their post.
