[Bro] no reports generated

[Jacob Yocom-Piatt]

bro-1.2.1 is now running on a 4.0-release openbsd machine here (thx j-p!) and
generating logs, however i got an empty report email this morning. i mean empty
as in there was no body to the email i received.

when i installed bro, i had to manually add the bro user and change ownership of
some of the directories in its install directory:

# ls -al /usr/local/bro

perhaps this has something to do with the empty report? i've looked through the
system logs and cannot find anything indicating why the report was not generated.

cluesticking appreciated.

cheers,
