Wrong key usage (0x19, 0x2) on key

[Chris Horry]

Hello all,

I noticed my key has started throwing this warning in new versions, it may
have been related to me trying to add an authentication key for my YubiKey
so I'm hoping I didn't mess it up.  I've done some Googling to see if
there's a way to restore it to normal operation without much success:

gpg: bad data signature from key <censored>: Wrong key usage (0x19, 0x2)

The two revoked subkeys were from my YubiKey experiments, I've since
created a separate key for that device and it's working just fine.

Any help appreciated, I just want to remove the warnings and hopefully get
reassurance my key is working.  I just use it for signing, certification
and encryption (and decryption).  Creating a new key is an option, but
would be inconvenient :(

Thanks!

Chris
