PDF input and SVG and PNG output

Using Poppler 0.18.1 utility PDFtoCairo with -svg option, the attached PDF produced the attached SVG result. When viewed there is a text and an image portion which can be seen to be tiled (in error).

When PDFToCairo with -png options is used, the attached png output is produced, which is correct.

I assume that poppler calls the same functions with the same data regardless of whether an SVG or PNG surface is used in Cairo. Meaning it's a Cairo problem.

I am not familiar with SVG and have been unable to find the precise XML node(s) or configuration causing the problem.

I found some of the particular nodes causing the problem in the SVG file.

Example) Find "<path style=" stroke:none;fill-rule:evenodd;fill:url(#pattern11);" d="M 513.839844 811.558594 L 26684.519531 811.558594 L 26684.519531 -27531.960938 L 513.839844 -27531.960938 Z M 513.839844 811.558594 "/>"

Then, D is way too big, and should start at 513.839844,811.558594 then draw a rectangle of dimensions ~ 55.76 x 58.375

General Problem) You'll see there are a few nodes with very large paths. Where do these come from?

Downloading the attached tarball and running the test8.pdf through svgtocairo -svg, the generated svg appears to display as intended.  I tested using:
  * inkscape
  * eog
  * firefox
  * opera

Can you verify the issue still exists?  If so, please give us some additional tips on how to reproduce the fault.
