I have a field collection that contains both an image and a geofield that's set to pull EXIF data from the image field. These are the errors I get:

Notice: Undefined index: fid in geocoder_exif_field() (line 36 of...

Line 36: if ($field_item['fid']) {

So I assume the Geocoder exif.inc is unable to find and fid on the image field in question.

This would also seem to be an issue with Field Collection, not Geocoder. I did not post anything in Geocoder issues.

Please correct me if I'm wrong :)
