            Bug ID: 317183
           Summary: okular/poppler crashes when printing a deleted PDF
                    file
    Classification: Unclassified
           Product: okular
           Version: 0.16.1
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: faure at kde.org

Application: okular (0.16.1)
KDE Platform Version: 4.10.1 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.7.10-1.1-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

I opened a PDF that was attached to a mail, in kmail. I.e. okular was showing a
temporary file.

Then I switched to another email in kmail -- which deleted the temporary file.

Then I tried to print the PDF -> okular crashed.

(I think it can also crash when just scrolling around the document, I had that
before.)

If the PDF is loaded on demand, I guess there's no way to actually make this
work. But maybe it could detect this case, and show an error message rather
than crash.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
