Is it possible that the file has been corrupted for example by a merge
of some status output or debug messages of a frontend (mutt?) into the
data stream?

I dont think that this is a problem with teh samrtdcard.  The problems
occurs during bulk decryption and not whule decrypting the session key
with the smart card.  However it is in theory possible that the
smartcard code printed debug messages to stdout. 

CR/LF <-> LF mapping somewhere?
