Parameters in URL create a 502 server error when using print_pdf_generate_path() to email a PDF

Hi

The FAQ entry describing how to email a PDF using print_pdf_generate_path() is working well, unless there are URL parameters in the path.

Is this expected / intended behaviour? I've found it possible to generate downloadable PDFs using the same path (including the parameters), from the PRINT_PATH defined in print_menu().

Thanks for a really useful module.
