[PATCH] fix pixbuf_get_page_size with null parameters

[Jeff Muizelaar <jrmuizel nit ca>]

Attached patch is really straight forward. The parameters to get_page
can be null, make sure we check before assigning.

	* pixbuf/pixbuf-document.c: (pixbuf_document_get_page_size):
	
	check for NULL before assigning to width and height parameters
