            Bug ID: 322739
           Summary: okular crashes while saving annotation to okular
                    document archive
    Classification: Unclassified
           Product: okular
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: bernhard.marx at gmx.net

As the KDEcrashhandler chocked on the Version (0.16.60), I paste it's output
here:

Application: okular (0.16.60)
KDE Platform Version: 4.8.4 (4.8.4) (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-4-686-pae i686
Distribution: Debian GNU/Linux 7.1 (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:
I opened an okular document archive that already contained many annotations. I
added many more annotations. When saving the document archive I chose the same
name and agreed to the dialog asking whether I wanted to overwrite the existing
file. Then okular crashed. 
The file however was saved. It can be opened by okular and contains all the
notes that were recently added.

- Unusual behavior I noticed:
This was not the first time this happend. But this time bonnie++ was doing hard
drive benchmarks in the background, system load was between 2 and 4 at the time
of the crash. 

On this debian system I have installed the regular debian package
(stable/wheezy) and a version compiled from git sources. The latter one was
crashing. However, I cannot report a crash with "Application: okular (0.16.60)"
so will try "using Devel" instead.

The crash can be reproduced some of the time.

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