Can't import with multiple identities

I can't import my key, it has multiple identities on it, which I can only make a guess could be related to the issue since generating a key works.

Here's the output of both keys (first is existing, second is generated by keybase):

```

```

EDIT: the error, can't believe I forgot:
ERROR openpgp: invalid data: entity without any identities

The report concerns importing an existing GPG key with multiple identities and includes the error “entity without any identities” plus sample key output. Start by reproducing the import with the provided multi-identity key; no files or tests are named, so locate the import path from the error and verify that the key imports successfully with its identities retained.
