           Summary: okular crashed while reloading a pdf file
           Product: okular
           Version: 0.12
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: okular-devel at kde.org
        ReportedBy: yabolus at gmail.com

Qt Version: 4.7.1
Operating System: Linux 2.6.37-pf2 x86_64

-- Information about the crash:
- What I was doing when the application crashed:
I was writing a document in latex. I rebuilt the pdf file, Okular tried to
reload it and crashed. I tried rebuilding it a few times and was able to
reproduce the issue, but it crashed only some of the times. I can upload a pdf
file that does this on request. It happens with at least 2 different files
(both generated by pdflatex).

The crash can be reproduced some of the time.

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