I am trying to get my firejailed Claws Mail working with encryption (gpg, Nitrokey Storage 2). gnupg is already whitelisted in the claws mail firejail profile but it seems to not work with the Nitrokey. It´s a bit odd to describe but only one interaction with the Nitrokey is possible until Claws Mail freezes.
For example if I receive an encrypted mail I can enter the PIN for the Nitrokey. After that everything freezes. Same goes if I try to encrypt a mail.
Any idea what to change in firejail?
