No problem. Sorry about sending email direct - didn't realise that this 
list doesn't have Reply-To set. I'll have to keep an eye on that one...

That sounds like exactly the problem I'm seeing. Its not life 
threatening <g>, but it is a pain, since both Vector and Zenwalk have 
used .tlz packages in the past, and are only slowly moving to .txz.

I assume that it must be an error in the way the regex is structured, 
but I certainly can't see it.
