Using these files and “systemctl restart polkit.service” made it work for me again:

daubsi@bigigloo  /usr/share/polkit-1/rules.d  cat 03-polkit-pcscd.rules  
polkit.addRule(function(action, subject) {  
if (action.id == “org.debian.pcsc-lite.access\_pcsc” &&  
subject.user == “daubsi”) {  
return polkit.Result.YES;  
}  
});

polkit.addRule(function(action, subject) {  
if (action.id == “org.debian.pcsc-lite.access\_card” &&  
action.lookup(“reader”).startsWith(‘Nitrokey’) &&  
subject.user == “daubsi”) {  
return polkit.Result.YES; }  
});

Though, what I observe, is, that the commands execute all much more slowly now …?
