Problem viewing pdf-documents encrypted with zero-key over the net with firefox.

["Fredrik Ohrstrom" <oehrstroem gmail com>]

I use evince as my pdf-viewer inside firefox.

In mozpluggerrc I have written:
repeat noisy swallow(evince) fill: evince "$file"

Which works good on most sites,
but if I go to:
http://v3.espacenet.com/textdraw?DB=EPODOC&IDX=GB562228&F=0&QPN=GB562228

It will incorrectly ask for a decryption key. Whereas xpdf works fine.

I believe it has something to do with that the document is encrypted
with an encryption key that is zero. (Do not ask me why...)

Any solutions to this?

Thanks for a great document viewer!
