Hello Wytze,

Thanks a lot for your bugreport!

That's nice.  Are you processing just apache and bind logs?  Or also
other types?  BTW: Egon is working on a exim convertor.  In a while,
we'll be able to process also logfiles from the exim MTA.

You are absolutely right.

The error message shouldn't be there: a "bogus" message should never
occur, not even when random noise is fed to the scripts.

I just fixed it.  I'll upload a new tarball one of these days (so that
we finally get decent time handling in our release.... (see my previous
message to this list.))

Bye,

Joost
