Parsing not well formatted /etc/libccid_Info.plist causes invalid pointer error.

[dannywillems]

By mistake, I added two lines instead of one in one section of /etc/libccid_Info.plist, and i got this error.

➜  monero ./monero-wallet-cli --generate-from-device MoneroWallet --subaddress-lookahead 3:200

Please report to the libpcsclite bug tracker (don't know where that is offhand though).

[dannywillems]

@moneromooo-monero reported here LudovicRousseau/PCSC#43

[moneromooo-monero]

Can you please supply the info upstream requested to they can debug it ?

[moneromooo-monero]

libpcsc-lite is now gone, replace by libhidapi.

I'll close this since it is no longer applicable to monero, but upstream would like to get the information requested in LudovicRousseau/PCSC#43 to debug further since it appears to be independent of monero.
