[PGPME] Help with deleting keys

I am looking for some assistance with deleting keys using
pgpme_op_delete. The code I am working on is part of a Perl XSUB which
will accept a text string and delete all matching keys. When I call the
function below, however, it returns the proper list of keys (claiming
that they have been deleted), but but pgpme_op_delete returns
GPGME_No_Error and fails to delete the keys. Earlier today, I tried
putting pgpme_op_delete within the pgpme_op_keylist_next loop below,
but was getting a return code of GPGME_Busy. I am assuming that this
was because the keychain was open for reading.

What is the proper way to search for and delete specific keys? I even
tried releasing and re-creating a new context between the end of
pgpme_op_keylist_next and pgpme_op_delete. No dice.

I am only trying to delete public keys and am using gpgme-0.3.14 built
from source.
