[leafnode-list] leafnode-2.0.0.alpha20090908a.luascript filters killing all articles

[jh]

Just moved from leafnode-2.0.0.alpha20081120a to
leafnode-2.0.0.alpha20090908a.luascript. The filter file that worked
previously, now results in all news being killed. A simple example
filter of:

### do not accept articles older than 20 days
newsgroups = .*
maxage = 20
action = kill

### do not fetch articles beyond 100,000 bytes
maxbytes = 100000
action = kill

results in harmless articles being killed, thusly:

Nov 21 16:28:04 roo fetchnews[18680]: store: article header rejected by
filter: From: '<not-yet-seen>', Date: '<not-yet-seen>', Subject:
'<not-yet-seen>' Nov 21 16:28:04 roo fetchnews[18680]:
gmane.comp.lang.ruby.general: 0 articles fetched (to 25770), 1 killed

Grateful for any clues as to resolve this. (OS is Ubuntu 9.10).
