This is strange i think that swfdec-gnome-2.24.0 has a strict dependency on swfdec 0.8.x.

I've tried all the files with git rtmp branch here and while not perfectly they mostly work if you play them directly from the site. The issue you are having is that swddec is blocking your access to remote data from a local file and in this respect it is working like adobe flash player. See warning below:

SWFDEC: WARN : swfdec_load_object.c(166): swfdec_load_object_load: SECURITY: no access to http://www.picwing.com/albums/show_album_pictures?format=xml&submission_email_address=chumbysample&r=1229856811901&device_id=undefined from file:///

Since swfdec goal is to behave exactly the same way adobe player does it is doing the right thing.
