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 Internal Error: xref num 27 not found but needed, try to reconstruct<0a> Tagged: no UserProperties: no Suspects: no Form: none JavaScript: no Pages: 8 Encrypted: yes (print:yes copy:no change:no addNotes:yes algorithm:AES-256) Page size: 612 x 792 pts (letter) Page rot: 0 File size: 1626771 bytes Optimized: no PDF version: 1.4
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.
