trouble listing keys in my private-keys-v1.d directory

[Maarten Nieber]

Hi,
until today I was using gpg only for pass (the linux password manager). Today, I played around with gpg and now I have 2 problems:
1. I'm unable to list the key that is used for pass
To list the keys, I use: gpg --list-keys. Some new keys that I added today are there, but my previous key that I used for pass is not there.Fortunately, I am able to use this key, so it exists! The gpg password dialog (that pops up when I invoke pass) tells me that it's an openpgp key with ID 89F615FB.
When I run kbxutil --stats ~/.gnupg/pubring.kbx, it tells me that indeed there is 1 openpgp key:
Total number of blobs:        2               header:        1                empty:        0              openpgp:        1                 x509:        0          non flagged:        1       secret flagged:        0    ephemeral flagged:        0
Looking at the file modification dates, I suspect that my previous key is stored in private-keys-v1.d, but this key is for some reasonnot showing up when I run gpg --list-keys
~/.gnupg $ ls -altotal 168drwx------  4 maarten maarten  4096 Jan  2 14:11 .drwx------ 68 maarten maarten 20480 Jan  1 17:59 ..-rw-------  1 maarten maarten  2649 Mar  5  2017 dirmngr.conf-rw-------  1 maarten maarten  5191 Mar  5  2017 gpg.conf-rw-------  1 maarten maarten     0 Mar  6  2017 .gpg-v21-migrateddrwx------  2 maarten maarten  4096 Mar  5  2017 openpgp-revocs.ddrwx------  2 maarten maarten  4096 Mar  5  2017 private-keys-v1.d-rw-------  1 maarten maarten  3607 Jan  2 14:11 pubring.gpg-rw-------  1 maarten maarten  3607 Jan  2 14:11 pubring.gpg~-rw-r--r--  1 maarten maarten  1362 Mar  5  2017 pubring.kbx-rw-------  1 maarten maarten    32 Mar  5  2017 pubring.kbx~-rw-------  1 maarten maarten   600 Jan  2 14:11 random_seed-rw-r--r--  1 maarten maarten   540 Jan  1 23:02 revoke.carnism.asc-rw-------  1 maarten maarten  5199 Jan  2 14:11 secring.gpgsrwx------  1 maarten maarten     0 Jan  2 11:02 S.gpg-agent-rw-------  1 maarten maarten  1440 Jan  2 14:11 trustdb.gpg

2. pass is complaining when I try to add a new password:
gpg: 89F615FB: There is no assurance this key belongs to the named usergpg: [stdin]: encryption failed: Unusable public key

My hypothesis is that somehow, by creating a few extra keys today, my previous openpgp key is not visible anymore. Can somebody explain why that might be the case, and help me to repair this?
Thanks in advance,Maarten
