Prestashop 1.6.1.5 error View PDF delivery slip - HTTP 500

[sassbar]

Hello

After Upgrading PrestaShop from 1.6.1.4 to 1.6.1.5 I got problem with generating pdf files for delivery slips. When try to generate PDF delivery slip using Firefox 46.0.1 it only show a blank white screen. Using IE 11 show a blank white screen and error HTTP 500.

But for invoices generate PDF's correct. In the previous version (1.6.1.4) all was fine worked (wasn't this problem).

Please help.

Hello

I has remembered that I can get more information when I switch Prestashop to debug mode.
In the debog mode I got following error string:
MyHost/classes/pdf/PDF.php on line 95

I has compared previous and new original PDF.php files near line 95 and has found difference:

New (bad - not work)
$template->assignHookData($object);

$this->pdf_renderer->createHeader($template->getHeader());
$this->pdf_renderer->createFooter($template->getFooter());
$this->pdf_renderer->createPagination($template->getPagination());  // it's a line 95
$this->pdf_renderer->createContent($template->getContent());
$this->pdf_renderer->writePage();
$render = true;

Wrong string (line 95) is: $this->pdf_renderer->createPagination($template->getPagination());


Old (good - it's work)
$template->assignHookData($object);

$this->pdf_renderer->createHeader($template->getHeader());
$this->pdf_renderer->createFooter($template->getFooter());
$this->pdf_renderer->createContent($template->getContent());
$this->pdf_renderer->writePage();
$render = true;

Old seems like new, but without 'wrong string'. I has commented it in the my new file and I can now to generate Delivery PDF files.
Why this string ($this->pdf_renderer->createPagination($template->getPagination()); ) was add in the new PDF.php file?
Maybe it neccessary?

Please let to know.
Thank you.
