Summary: Segmentation faults when logging in using smartcard

Initial Comment:
I can succesfully connect to a Windows TS using rdesktpp 1.7.1.
But when smartcard must be used to login, rdesktop crashes after having entered the PIN code, reporting a segmentation fault.

This can be fixed easily in the next version of rdesktop by adding a condition test in the body of the SC_xfreeallmemory function in the scard.c file.
the xfree call must be conditional, test that the datasize of the handle is not zero. This will do, rdesktop remains stable after that.

setup is tested with rdesktop package 1.7.1 downloaded from rdesktop.org, pcsc-litepackage 1.5.2-7, smartcard driver ccid package 1.3.9, and glibc package 1.12-1.80, on a laptop running 64 bits RHEL 6
