23.0.60; EasyPG and OpenPGP smartcard: process epg not running

[Luca Capello]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Hello,

please Cc: me, I'm not subscribed to the list.

I cannot use the EasyPG interface with my OpenPGP smartcard [1] and the
OmniKey CardMan 6121 USB [2]: the light on the reader blinks, EasyPG
asks me for the passphrase and then it gives the error below.  It
doesn't matter if the passphrase is correct or not and indeed the one
included in the debug message is wrong.

FWIW, gnus/pgg works without any problem with the same smartcard and
reader.

Thx, bye,
Gismo / Luca
