           Summary: Okular crashes when adding bookmark if bookmarks.xml is
                    corrupted
           Product: okular
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: okular-devel kde org
        ReportedBy: Regnaron web de


Version:            (using KDE Devel)
Installed from:    Compiled sources
OS:                Linux

If you replace okular's bookmarks.xml file with a corrupted one (an empty one for example), adding a bookmark crashes okular.

Steps to reproduce

1) Delete bookmarks.* in /home/kde4daily/.kde4/share/apps/okular
2) Create new empy bookmarks.xml file (touch bookmarks.xml) 
3) Start okular and open any document
4) Add a bookmark (CTRL-B)

Except that okular does not crash when just showing the current bookmarks, it shows the same behaviour as konqueror in Bug 153429
If both use the same bookmark backend, maybe the two bugs are related?

I use kde4daily r744670 and the backtrace for this okular crash is:
