           Summary: Crash while scrolling through thumbnails
           Product: okular
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: okular-devel at kde.org
        ReportedBy: christoph at maxiom.de


Application: okular (0.10.80)
KDE Platform Version: 4.4.69 (KDE 4.4.69 (KDE 4.5 >= 20100324)) (Compiled from
sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.31.12-0.2-desktop i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
While scrolling through the thumbnail list of the document reported at bug
232058 I got this crash. When I tried to reproduce, I got the same crash by
just starting okular with that file. Trying a third time, I got no crash and
was able to scroll through all thumbnails multiple times.

The crash can be reproduced some of the time.

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