Generating pdf using wickedpdf and wkhtmltopdf in rails 2.3

[mayararajesh]

I am working with rails 2.3 with wickedpdf and wkhtmltopdf. While generating pdf it works fine at first time. When i am generating the pdf at second time onwards it generates RunTime Error.
It shows the error like below.

RuntimeError in XXXXXController#xxxxxx_pdf

--PDF could not be generated!
--Error: Failed loading page file:///tmp/wicked_header_pdf_3705_0.html?page=1&section=&
subsection=&frompage=1&subsubsection=&topage=1&webpage=foobar&time=10:55 AM&date=20/03/14
(sometimes it will work just to ignore this error with --ignore-load-errors)
--Error: Failed loading page file:///tmp/wicked_footer_pdf_3705_0.html?page=1&section=&
subsection=&frompage=1&subsubsection=&topage=1&webpage=foobar&time=10:55 AM&date=20/03/14
(sometimes it will work just to ignore this error with --ignore-load-errors)
--QPaintDevice: Cannot destroy paint device that is being painted
--Segmentation fault (core dumped)

Please help me to solve the above issue
Thanks

Are you using the wkhtmltopdf_binary gem?
What version of wkhtmltopdf?
What operating system?

It looks like your issue may be the same, or related to this one:

Does removing the headers and footers stop the issue from happening?
