Hi all!
Giving this PDF
https://www.farnell.com/datasheets/2304760.pdf kpdf
requires a password to open it while firefox does not.
Anybody knows the reason for this?

Here kpdf requested access to kwallet - I rejected and it asked for passwd.
FF is not asking for passwd
perhaps strace to see what is happening?
For what it's worth, the file shows as encrypted (and slightly broken):

It might be that the original creators of kpdf didn't anticipate the possible
existence of encrypted files that weren't password-locked. Or it could be that
the file breakage is causing other problems.
