[tor-relays] 0.2.9.10 dir port warning

Just upgraded my relay 855BC2DABE24C861CD887DB9B2E950424B49FC34 to 0.2.9.10 and now I get a new warning in the log file:

Mar 13 12:02:22.000 [notice] Bootstrapped 100%: Done Mar 13 12:03:20.000 [warn] Cannot make an outgoing connection without a DirPort. Mar 13 12:03:21.000 [notice] Self-testing indicates your DirPort is reachable from the outside. Excellent. Publishing server descriptor.

Everything is working fine, just curious about the warning. Is it an actual problem with my setup or a quirk of 0.2.9.10?
