           Summary: Crash at KTextEdit::mousePopupMenu() when using
                    setTextInteractionFlags(Qt::NoTextInteraction)
           Product: kdelibs
           Version: 4.1
          Platform: SuSE RPMs
        OS/Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: kdeui
        AssignedTo: kdelibs-bugs at kde.org
        ReportedBy: mail at philipp-wagner.com


Version:            (using KDE 4.1.2)
Installed from:    SuSE RPMs

If you have a KTextEdit created like that:

KTextEdit *kte = new KTextEdit(this);
kte->setTextInteractionFlags(Qt::NoTextInteraction);

and then right-click on the edit field, the method KTextEdit::mousePopupMenu()
gets called
(http://api.kde.org/4.x-api/kdelibs-apidocs/kdeui/html/ktextedit_8cpp-source.html#l00394)

By defining that we want no interaction, Qt returns a NP at
createStandardContextMenu();

The application crashes when calling connect():

QObject::connect: Cannot connect (null)::triggered ( QAction* ) to
KTextEdit::menuActivated( QAction* )

I don't have a recent SVN checkout here to provide a patch, but it should be
done with a simple check for a NP.
