#35 "insufficient buffer" message with smartcard on Leopard
I have two keys: one key on my hard disk and one key on my OpenPGP smartcard. Both keys worked fine on Tiger.
Now, with Leopard, the key on my hard disk still works (using Enigmail on Thunderbird and GPG on the command line), but the key on the smartcard doesn't work anymore for decrypting or signing e-mails).
Accessing the smartcard looks like this:
galadriel:~ klee$ gpg --card-status
gpg: detected reader `SCR335 USB Smart Card Reader 00 00'
gpg: pcsc_status failed: insufficient buffer (0x80100008) 35
gpg: Ohhhh jeeee: ATR returned by pcsc_status is too large
secmem usage: 0/0 bytes in 0/0 blocks of pool 0/32768
Abort trap
Listing both keys still works fine, though:
galadriel:~ klee$ gpg --list-keys (my e-mail-address here)

A bug in pcsc-lite on Leopard will trigger a bug in OpenSC.
Try to upgrade pcsc-lite on Leopard using http://lists.apple.com/archives/fed-talk/2008/Jul/msg00023.html

The ZIP file provided on http://lists.apple.com/archives/fed-talk/2008/Jul/msg00023.html has a size of 0 bytes for me. Do others have the same problem? Is there maybe another download source for the update?
