GPG, OpenPGP card, ACS ACR30U card reader

[Tony Whitmore]

Further to my mails earlier this month, I've been trying to get GPG
working with my card reader and PC/SC.

pcscd recognises my card reader and the card that is inserted into it.
GnuPG returns the expected output from the --card-status command. I have
been able to set the language on the card, following the instructions on
the HOWTO. However, whenever I try to set my name on the card, GnuPG
exits with an error and pcscd segfaults.

$ gpg --disable-ccid --debug-all -vv --card-edit

Admin commands are allowed

pcscd produces this (output from after enter is hit after entering the
admin PIN):

Segmentation fault

I'd appreciate any advice as to where to look next. As I see it, this
could either be a bug in GnuPG, a bug in pcscd or a bug in the driver
for my card reader. But I'm not experienced enough to know where to look
to find out more.

Thanks in advance,

Tony

P.S. As per Jonathan Rockway's e-mail, the output of pcsc_scan on my
system (with pcscd running and the card inserted) is:
