[Enigmail] OpenPGP Card: fundamental problems

[Stefan X]

Hi Patrick!
Thanks a lot for your tip.

I open a shell, "unset GPG_AGENT_INFO" and execute Thunderbird
afterwards in the same shell. This solves the problem for me. I can use
the OpenPGP card without a problem. :-)

For my understanding the problem is that Seahorse does not support
smartcards but is used in Ubuntu as the default way for PIN handling.
Also disabling the option to use GPG Agent in Enigmail does not work for
any reason. If using smart cards, Seahorse does not work but GnuPG
itself would do a better job. So two questions are remaining:

1. I wouldn't like each time to start a shell, unset GPG_AGENT_INFO and
execute Thunderbird afterwards. There should be a more elegant
workaround. For my understanding unsetting GPG_AGENT_INFO in ~/.profile
 would not be a good solution because Seahorse may be appropriate in
other cases. So I would like to unset GPG_AGENT_INFO for Thunderbird
only. Maybe it is possible to define a alias "thunderbird" which unsets
the variable before executing the application? Or any other elegant
solution?

2. Should/Could this problem be fixed in Enigmail?

Best regards
Stefan
