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?

confirmed
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):
~ $ pdfinfo 2304760.pdf

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.
Thanks for the hint, now I kind of solved it by uploading the PDF to
https://smallpdf.com , let it remove the password and saving the result
:)
But what I still don't understand: why was the preview in konqueror
showing the first page of the pdf? Does KPDF not use the same component
to as konqueror?

If I remember correctly, poppler is used to display thumbnails, while KPDF
is based on XPDF.
