I have used DOMPDF many times before successfully, however outside of the Kohana Framework.

I created a module for DOMPDF and called it simply pdf. Here is it's code.

class Pdf {

    private $domPdfInstance;

    public function __construct($html) {
        if ( ! class_exists('DOMPDF', FALSE)) {
            // Load DOMPDF
            require Kohana::find_file('vendor', 'dompdf/dompdf_config.inc');
        }
        $this->domPdfInstance = new DOMPDF;
        $this->domPdfInstance->load_html($html);

    }

    public function render() {
        $this->domPdfInstance->render();
        return $this;
    }

    public function stream($filename) {
        if (pathinfo($filename, PATHINFO_EXTENSION) !== 'pdf') {
            $filename .= '.pdf';
        }

        $this->domPdfInstance->stream($filename);
        return $this;
    }
}

For some reason, any PDF I generate using this results in it being corrupt (not opening under Mac OS X's Preview app at least).

I have even tried this basic HTML

    <html>
        <head>
            <title>PDF</title>
        </head>
        <body>


        please work
        </body>
    </html>

Is this a known problem? I have not touched anything in dompdf_config.inc.php except uncomment out the error reporting levels so they now read

error_reporting(E_STRICT | E_ALL);

PHP is not reporting any errors.

Here is a screenshot of the error from Preview (though I think it's probably unhelpful)

Preview Error

Some thing I have thought may be a problem

Auto loading conflicts
Base path conflicts
