Compiler:          gcc version 3.4.4

I was exercising a KDE app tutorial:
http://developer.kde.org/~larrosa/visualtutorial/chapter04.html

When I fill out the initializing constructur of class CentralViewBase, KDevelop crashes:

CentralView::CentralView( QWidget* parent, const char* name, WFlags fl )
 : CentralViewBase(paren !!!<== CRASH while typing!!! )
{
}


These are the messages on the terminal:
