Password protected pdf file which KPDF fails to open (47.19 KB, application/pdf)

Description Ritesh Raj Sarraf 2007-02-24 11:50:12 UTC
Version:            (using KDE KDE 3.5.6)
Installed from:    Debian testing/unstable Packages

kpdf is not able to open password protected pdf files.
I've checked the same with xpdf and it can open the password protected pdf files.

The PDF files are my bank statements from Citibank (India).
kpdf never prompts for a password. It just errors out complaining that it couldn't open that particular pdf file.

If I try "Open with XPDF", xpdf prompts me for the password and then opens the file. So this definitely is a kpdf bug.

I had filed a bug in the Debian database (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=369994) but had completely forgotten to file it here. Hope this'll get resolved in 3.5.7.


Thanks,
Ritesh

Do you have any errors on the console if you start KPDF from there?
What happens if you try opening the document with 'gv'?
Comment 2 Ritesh Raj Sarraf 2007-02-24 13:30:04 UTC
Opening with kpdf from the console still doesn't give any messages on the console.

When I tried with gv, I got the following errors on the console:
rrs@geeKISSexy:/tmp/kde-rrs $ gv VISA\ PREFERRED\ INTERNATIONAL\ -\ GOLD.pdf

any change we get one of those pdf that fail with kpdf and work on xpdf?
Comment 4 Ritesh Raj Sarraf 2007-02-26 09:25:28 UTC
Hi Albert,

That's my back account statement. It would be difficult for me to give it. :-(

If you want me to try something and report back, please let me know. I'll be happy to do that to find the bug.

Password protected pdf file which KPDF fails to open
Comment 6 Albert Astals Cid 2007-04-09 13:21:27 UTC
That file is not a pdf file, PDF files must end with %%EOF and this one ends with %%EO, once corrected the file works correctly
