Cannot print CSS background for pdf

[jwhipp]

When I try to set --pdf-background 1 when generating a PDF, I am met with a fail message and the process hangs.

Command Line:

xvfb-run URL 1024 --format pdf --filename "myfile.pdf" --pdf-margin none --pdf-page-size legal --pdf-background 1 --debug

Output:

Also, then I leave out the --pdf-background, the PDF generates but it's missing the background image specified in the CSS.
