           Summary: massif-visualizer crashes due to bad kgraphviewerpart
                    library
           Product: massif-visualizer
           Version: 0.2
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: massif-visualizer at kde.org
        ReportedBy: c.lusby at gmail.com


Version:           0.2 (using KDE 4.5.2) 
OS:                Linux

Standard ubuntu kgraphviewerpart library lives in:
/usr/lib/kde4/kgraphviewerpart.so

Installation from latest git installs to:
/usr/local/lib/kde4/kgraphviewerpart.so


massif-visualizer crashes as the kgraphviewerpart is not loaded correctly (null
pointer). Fixed by making the kgraphviewer.so a symlink to the git install.
Probably need extra checks at startup for this.
