PDF causes memory leak and huge CPU load after re- opening the URL

When opening in a tab memory consumption increases by around 250-300 MB. Closing that tab will not release that memory.

After three or for times opening that URL again, which happens more often when the browser is open the whole day (as its usual for me) the CPU goes crazy and memory consumption goes up to 1.8 GB. With that trashing the disk and getting completely unresponsively. Closing the browser in this case is not possible any more, i have to kill it and with perform a session restore after restart
Seems something fishy is going on with the images in the PDF.
