When T=0 protocol is used a case-4 can NOT contain a Le.

The (overall) result is so undefined, the card may choose to not 
respond, or the firmware or diver may generate an error (or for some 
maange itself the Get Response).

AFAIK, your error is not related to a specific Gem+ driver but due to an 
invalid use of the protocol.

Rgds,
