           Summary: Okular crash during scroll
           Product: okular
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: okular-devel at kde.org
        ReportedBy: rad.n at centrum.cz


Application that crashed: okular
Version of the application: 0.8.80
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.29.4-167.fc11.x86_64 x86_64

What I was doing when the application crashed:
Okular crashes randomly during quick page switching. I'm not able to reproduce
it, but it occures quite often. It happens with Okular from KDE 4.2.85 (4.3
beta1) but it never happened with 4.2.3 that I used before.

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