Security event log reads correctly, custom event log (HAT) spews error. Any thoughts?

hostlist.ini:
localhost,security,hat

What I see in lassotrace.log:

0x007f02: 09/09/2009 16:02:16 [Lasso v4.0.5](ServiceMain:1976): Warning: LSupport::setParams( ... ): wrong log type format (hostlist.ini: @line 1, char 19). Reading ignored.
