           Summary: scrolling complex PDF crashes before anything is
                    painted [__libc_message, malloc_printerr,
                    psh_hint_table_done]
           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: mpartap at gmx.net


Application: okular (0.9.80)
KDE Version: 4.3.70 (KDE 4.3.70 (KDE 4.4 >= 20091002)) (Compiled from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.31-gentoo x86_64
Distribution (Platform): Gentoo Packages

What I was doing when the application crashed:
This
http://www.avv.de/web/download/netz/region_aachen.pdf
PDF crashes right after being opened. Try to pan the white page -> crash
bt is different then that of #199250 or #201875

 -- Backtrace:
Application: Okular (okular), signal: Aborted
87      int result = INLINE_SYSCALL (poll, 3, CHECK_N (fds, nfds), nfds,
timeout);
