DKIM temperror's from yahoo

I'm hoping someone here has some experience with sending DKIM signed
messages to Yahoo. We are successfully signing our outbound emails, and
Gmail is accepting the signature:

Authentication-Results:; spf=pass ( domain of designates as permitted
sender); dkim=pass

However, Yahoo is saying the DKIM authentication is failing with a

Authentication-Results:; domainkeys=neutral (no sig);; dkim=temperror (multiple keys)

Has anyone seen this error? We are only publishing one key in DNS, so
I'm not sure what "Multiple Keys" is referring to. I can't seem to find
any information about this on the web.

Any ideas would be greatly appreciated.

Here are my DKIM and DKIM Policy records published in DNS:

062010._domainkey IN TXT "k=rsa\;
AB" ;New DKIM Record

_domainkey IN TXT "t=y; o=~;" ;DKIM Policy
Record (not all emails are signed)
