Missing certificates

[Ian Goldberg]

Every time I launch 0.2.3, I see these messages:

Dec 02 08:13:06.000 [notice] We're missing a certificate from authority
with signing key F7C7B9191C74C0BA07363C84D37BBAD3A8A6C6D8: launching
request.
Dec 02 08:13:06.000 [notice] We're missing a certificate from authority
with signing key 604834622B54F2D9BA39B34AC53924546733AA60: launching
request.

Whose certificates are these, and why are we continually missing them?

Thanks,
