I'm using Page Preview with a site that uses the GeoPHP module. Page Preview appears to trigger an exception when you try to preview a content type page that uses geophp.

Exception: geoPHP could not find an adapter of type in geoPHP::load()

I've followed up on GeoPHP related issues and am not finding any problems so I'm guessing it's something related to Page Preview. Is there any reason why this would be occurring? It works perfectly well with other content types that don't use any location based fields.
