Seg fault when using custom shape with linked svg

[KillBoy PowerHed <killboy_powerhed yahoo com au>]

Hi list,

Looking for a little help with $subject... I've been revamping an old script which worked a couple of years back, I'm wondering if things have changed in regard to svg support. Below is the shape, sheet and directory layout, any assistance on how to proceed would be gratefully received

thanks.
