thanks for all the advice and apologies for the noise. It turns out that Victor Stinner's recommendation in the dev list 
was the solution as I don't see the segfault with pillow built from latest git

Pillow @ git+git://github.com/python-pillow/pillow.git@8dc5f692dbd9a418d8c441f0e2aa09a3f5c03508

I did realize that this must be a late issue in the process as the pdf was being produced and written as expected and 
that is normally the end of things
