I don't think so. You report that the first program which uses the card
(either gpg or ssh) "keeps" it, and the other is unable to (btw, would 
e.g. a second sign work?). This looks like the first one locks use of
the card.
May gpg and ssh be launchihng separete scdaemon instances? Does it help
if you use --card-timeout on scdaemon config?
