Mac OS X error

[Ben Weintraub <benwei u washington edu>]

Hi,
I got f-spot running on Mac OS X using darwinports and a small amount 
of tweaking, but I keep getting the same errors experienced by Niklas 
Saers as described here:
http://mail.gnome.org/archives/f-spot-list/2005-January/msg00035.html

I had been using f-spot 0.0.7, but decided to try CVS just to see if it 
was fixed there, but got the same error.  Here it is just so you don't 
have to go back and look at the other email if you don't want to:

flapjack:~/f-spot/f-spot/src benwei$ sh f-spot
*** Running uninstalled f-spot ***

Unhandled Exception: System.NullReferenceException: Object reference

Nobody seems to have replied to Niklas's query, and I'm wondering if 
anyone knows what the problem here is?  Should I not even bother with 
trying to get it to run on Mac OS X?
Thanks,
Ben
