           Summary: Crash while scrolling through chm file
           Product: okular
           Version: unspecified
          Platform: Archlinux Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: okular-devel at kde.org
        ReportedBy: iberlynx at lavabit.com


Application: okular (0.10.4)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.34-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
I was trying to scroll through a chm file and it stopped opening new pages, I
tried to scroll down further but later it crashed.
I'm not sure if it was trigered by something related to not opening the next
pages, because at this time I pressed F7 to jump to another page.

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