           Summary: Okular Crashes When Opening a PDF Document In Firefox
           Product: okular
           Version: 0.11.2
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: okular-devel at kde.org
        ReportedBy: jarray52 at gmail.com


Application: okular (0.11.2)
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.1
Operating System: Linux 2.6.35.11-83.fc14.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
Okular crashes as a result of a segmentation fault whenever a pdf document is
opened from inside Firefox. This happens with every pdf document, and the
segmentation fault demonstrates it's a bug inside okular. While other bug
reports were opened and then closed after a fix was made, the bug still exists
even though a fix was pushed through to Fedora 14 updates. Hence, I opened a
new bug report.

The crash can be reproduced every time.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
