Missing key from authority?

[Tom Hek]

Hello,

This message started flooding my logs: Jan 09 22:19:27.260 [notice]  
We're missing a certificate from authority tor26 with signing key  
0000000000000000000000000000000000000000: launching request.

A friend of my has exact the same message flooding over his log. We  
are both running 0.2.0.15-alpha. OS on my box is FreeBSD and on his  
box Debian, so I think this message is not OS related but it's related  
to the authority. Is someone else having the same message lately?

Tom
