Yep, unfortunately it would appear the same or identical issue does
occur with a speedo build of 2.1.2. The issue is essentially that
smartcard works for the first time but once some-indeterminate-time has
passed, gpg just hangs. No pinentry, nothing just happens. /Will need to
troubleshoot this further on 2.1.2 to try to find out more./

I think we might want to move some of this discussion to gnupg-devel
side at some point.
