With the code the way it is in CVS, I can use both the calendar I'd 
been testing
on from icalshare.com (http://homepage.mac.com/ical/.calendars/Flyers.ics) and
your Smallville one and have events show up properly. If I revert the
greediness change, remove the /U at the end of the regexp, or both, then no
events show up. Your experience, actually, sounds exactly like what I was
seeing *before* I made that commit.
