Bug#1117638: openssh-client 10.1p1-1 fails to read smart card

Package: openssh-client
Version: 10.1p1-1
Severity: serious

When attempting to read a smart card via

          PKCS11Provider /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so

the following error is seen in the trace:

debug1: pkcs11_start_helper: starting /usr/lib/openssh/ssh-pkcs11-helper 
-vvv
debug3: pkcs11_init: called, interactive = 0
debug1: process_add

Note the line "pin required";  however at no time does a prompt for a 
PIN occur.  Back-revving to 10.0p1-8 fixes this, it prompts for a PIN, 
and the trace shows:
