I still don't understand, but it would be nice if you could do your
tests with the last version, v20, even if the changes are just cosmetic.

Yes. It looks like the guest sees the ccid device (that's the Gemplus,
you can see it's qemu if you do lsusb), but no card. The reason for the
later is that spicec didn't see any card. That's why I suggested trying to
run spicec as root - the bottom line is that you need to make sure NSS
can see the device as a regular user. I'll try to supply better instructions
later.
