[Enigmail] Problems signing message (gpg-agent related?)

[James Davis]

Sorry for the verboseness of this post...

I'm using Icedove 1.5.0.12, Enigmail 0.94.3 and gnupg 1.4.6 on Debian
4.0, I also have gnupg 2 available. I'm using a smartcard with an SCR335
reader through the internal CCID driver. I think my problem relates to
gpg-agent as I'd recently been tweaking the configuration but I can't
figure out how this is resulting in what I see.

When I try to sign a message with enigmail I get the following error
(from log directory)

[GNUPG:] BEGIN_SIGNING
winscard_clnt.c:3232:SCardCheckDaemonAvailability() PCSC Not Running
gpg: pcsc_establish_context failed: no service (0x8010001d)
[GNUPG:] CARDCTRL 5
gpg: card reader not available
gpg: signing failed: general error
gpg: [stdin]: clearsign failed: general error

The gpg command enigmail ran was

/usr/bin/gpg --charset utf8  --batch --no-tty --status-fd 2 --comment
'Using GnuPG with Mozilla - http://enigmail.mozdev.org' --digest-algo
sha1 -t --clearsign -u 0x890F159E --passphrase-fd 0 --no-use-agent

The following command fails

$ echo "Hello world" | gpg --charset utf8  --batch --no-tty --status-fd
2 --comment 'Using GnuPG with Mozilla - http://enigmail.mozdev.org'
--digest-algo sha1 -t --clearsign -u 0x890F159E --passphrase-fd 0
--no-use-agent
[GNUPG:] BEGIN_SIGNING

but the command succeeds when I remove "--passphrase-fd 0
--no-use-agent" from the command.

Any ideas?
