           Summary: Fail to open encrypted PDF, which opens with Acrobat
                    Reader.
           Product: poppler
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
        AssignedTo: poppler-bugs at lists.freedesktop.org
        ReportedBy: alberto at matracas.org


The file is an AES-256 encrypted PDF 1.7 file, available at:

http://www.bli.uni-saarland.de/lehre/Studienangebot%20Exi%202009-2010/Handout%20Management%20und%20Rechnungswesen%20WS%202009_2010.pdf

I have the correct password, and it opens in Acrobat Reader 9.2.

Evince asks for the password, but then rejects it as invalid.
In the console, it prints the following:

Error: Weird encryption info
Error: Incorrect password

This also happens with InkScape, although it does not seem to have any way of
requesting the password.

Other unrelated PDF handling programs fail analogously: pdftk says "Error:
Failed to open PDF file" even when given the correct password. I mention this
because it would seem to point towards changes in the PDF format and not wrong
implementation of previous versions of the specification.
