Crashes on fedora 15 (python 2.7.1)

Hi,

After installing gaphor on fedora 2.7.1, attempting to launch it
resulted in:

$ gaphor

Poking around in the source code, it looks like at some point Zope
stopped liking a direct call to component.registry. Not sure why that
would happen, exactly. At any rate, this patch fixes the problem for
me:
