[Cod-bugs] problem using RESTful API with json format

[Corrado Cuocci]

Dear developers of COD,

I have found a possible bug when you query the COD by using the RESTful 
API in the following conditions:
1) json format but not html
2) el1 or nel1 keywords associated to some elements (C,H,O)

To reproduce the problem try for example the following query:
http://www.crystallography.net/cod/result.php?el1=C&format=json

String error is:
"Error downloading 
http://www.crystallography.net/cod/result.php?el1=C&format=json - server 
replied: Internal Server Error"

Best regards
Corrado
