I have a crash because the APDU "00 A4 00 00 02 49 46 00" failed at
the PCSC layer (SCardTransmit() Card not transacted: 0x80100016)
So selected_file is then NULL but the code tries to access
selected_file->size. Crash!
The value of r, the returned value of sc_select_file(), is strange to me.
What should be the correct way to handle this case in the code?
Side note: the SCardTransmit() failed because OpenSC tried a secure
verify pin that was rejected by the reader and the CCID driver have a
bug in that specific case with a T=1 card and a TPDU reader (now
corrected).
