Which of our tools is giving you problems? GPG Mail possibly, or something related

Attach a screenshot of the version info for all installed components (how to:

Describe your problem. Add as much detail as possible. If I try to sign something with the key stored on my Yubikey, eveything works fine from either the command line, or Finder -> Services -> OpenPGP: Sign File.

If I then open up Mail with GPG Mail loaded, signatures fail both in GPG Mail and in the command line and in Finder with a card error.

What did you expect instead

For signing to keep working even after Mail is opened

Describe steps leading to the problem.

Insert card:

~$ gpg --clearsign testfile.txt
gpg: using "<my key id>" as default secret key for signing
GPGTools asks me to unlock my card and everything works fine.

I then open Mail and view an encrypted email, GPGTools asks me to unlock my card again for some reason, and then I try creating another signature:

~$ gpg --clearsign testfile.txt
gpg: signing failed: Card error
gpg: plextest.txt: clear-sign failed: Card error

Are you using any other plugins?

    I should add that I've tried quitting and restarting as well as killing and restarting gpg-agent and scdaemon with gpgconf --kill gpg-agent followed by gpg --card-status.
