Adding new uid to causes bad signature

[Eva Bolten]

Hi,

I have tried to replicate your issue using a Yubikey 5 NFC, doing what you 
did.

> gpg> adduid
> gpg> save

For my key and using gpg 2.4.5 on a standard Windows 10 system "check" didn't 
give an error and signing a document worked without any issues.
I used a simple brainpool standard testkey with only one subkey, though.

Importing your second pubkey did not change anything noticeable, gpg reported 
no changes on the key and there is no new UID to be seen.
So it seems it was not exported. To avoid any confusion does 

  gpg -k 408FB2EBC3DF3DBBE0143D9A29AD46D6F58287A3

show the new UID for you?

Is there additional info if you add "--list-options show-unusable-uids" 
before the "-k"?

Regards

Eva
