[Enigmail] Smartcard: encryption doesn't work

[Thomas Hühn]

Hi

I have an OpenPGP card and can use it with gpg.

But I have problems with Enigmail. I can encrypt mails (MIME and
non-MIME), but as soon as I try to sign them it fails with "Es wurde
keine Smartcard im Lesegerät gefunden" (no smartcard found in reader).

"OpenPGP --> Smartcard verwalten..." finds the smartcard with all three
subkeys present (although no creation date is shown).

I have created those subkeys locally on the PC and transferred them to
the card via keytocard.

I can sign files with gpg, only Enigmail fails.

Any ideas?

Thanks
Thomas
