           Summary: Okular crashes after reloading of a regenerated dvi
                    file failed
           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: possebaer at gmx.at


Application that crashed: okular
Version of the application: 0.9.4
KDE Version: 4.3.4 (KDE 4.3.4) "release 2"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.8-0.1-default i686
Distribution: "openSUSE 11.2 (i586)"

What I was doing when the application crashed:
This occurs when I work with kile on a latex file. I let the preview of the
according dvi open in okular 
when rebuilding the latex file. Sometimes (not always) the automatically
reloading of the regenerated dvi file fails, especially if there were errors in
the latex run. After the reloading failed okular seems to hang, and after I
close okular it crashes with this backtrace.

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