           Summary: segmentation fault in createMenu
           Product: kde
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: eugene.hermann at gmail.com


Application that crashed: kdevelop.bin
Version of the application: 3.9.98 (using KDevPlatform 0.9.98)
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-18-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
- start kdevelop
- open session
- right click on editor window

Look how the KDevelop::VcsPluginHelper::VcsPluginHelperPrivate::createMenu has
falled.
