            Bug ID: 326056
           Summary: Okular crashed after PDF update with latex
    Classification: Unclassified
           Product: okular
           Version: 0.17.2
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: martin.ruessler at gmx.net

Application: okular (0.17.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-31-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:

I was viewing a PDF in Okular (externally opened) and compiled a new version of
the file when the program crashed.

I found an old bug report from 2010 which seemed to be related but it was
marked as fixed. Maybe it is a regression?
