           Summary: Okular crashes during scroll [QList<QPolygonF>::free,
                    QX11PaintEnginePrivate::fillPath,
                    QX11PaintEngine::drawPath]
           Product: okular
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: okular-devel at kde.org
        ReportedBy: xtom.vavra at gmail.com


Application: okular (0.9.80)
KDE Version: 4.3.74 (KDE 4.3.74 (KDE 4.4 >= 20091102)) (Compiled from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.31-trunk-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
I am opening http://shoppardubice.jip-napoje.cz/editor/filestore/File/alko.pdf
this file and during scroll to second page I am getting this crash. I am using
now kde-qt 4.6-stable-patched with KDE trunk (updated almost every day)
