Ok shame on me... I got confused with the TransferSyntax called: 
"Unknown Transfer Syntax".

Anyway I still don't understand why gdcm-bcc55 start failing on ACR-NEMA 
only 8days ago (did you see the NULL I added at the end of special 
transfer syntax). Are you sure nothing else change, because without 
NULL, we should have seen this bug a long time ago...

my 2 cents
