Take the address of the zoom_rect structure member like this:

    newSVGdkRectangle (&settings->zoom_rect)

You need to dereference the pointed that SvGdkRectangle() returns.

    settings->zoom_rect = *SvGdkRectangle (*svp);

SvGdkRectangle() is implemented as gperl_get_boxed_check(), which does  
not allow undef, so you should not get a NULL pointer back from it  
unless something is quite wrong.
