EDIT

The according media page (http://www.palmweb.org/?q=cdm_dataportal/media/c3ab3ef1-7983-4ca3-afdf-c4476fdec835) of the image shows some of the metadata, but not all of them. There is a minor irregularity in the image itself which may cause the problem. It is found in the IPTC field 'Chraracter Set' which seems to contain some special characters.

Our server in fact dislikes something in the meta-data and fails with an error.

The server must be more robust against non standard characters in the meta data.

the server error:
