IPhoto crashing when setting up access to Flickr

Question

I posted this a while back but nobody answered so I'm trying again.
Can anybody tell me what's going wrong here and how I can fix it?
iPhoto 11 consistently crashes when I try to set up Flickr access. I've tried deleting the preference files and rebuilding the database.
Here's a crash report:

Answer 1

I have set up the group folders and set
which group folders belong to which user.
That is a bit confusing but basically...
If you only want individual users to see 'their' folder, use the owner permission and set group and other to 'none'. Disallow 'guest' access.
If you want groups to see their group folder, ignore the owner permission and concentrate on group permissions. Set 'other' to none. Disallow 'guest' access.
But
for some Reason I cannot get rid of the folders I
want to get rid of such as the groups folder. The
workgroup manager doesnt allow you to delete the
folder.
Switch off sharing for the folder first.
