Idon't know how you made it crashed. But I clicked on one of the menu items 
and got:

and got:

bash-2.05b$ ./beirc
Fatal error: you need to have a KInstance object before
you do anything that requires it! Examples of this are config
objects, standard directories or translations.
Abort trap (core dumped)

If you didn't see this, then I guess you must be using a distribution release 
of KDE with all debugging turned off, which will be very hard to use for 
development. Best compile your own KDE with --enable-debug.

So the basic problem. You have a Qt application (QApplication) and you've 
tried to use KDE stuff in there. This won't work. Change it to KApplication 
(which will give you the KInstance you need -- you could also create it 
manually I guess but that seems to be asking for more trouble than it's 
worth).

Make main.cpp look like this and it will work:

#include <kapplication.h>
#include <kaboutdata.h>
#include "mainwindow.h"
#include <kcmdlineargs.h>

int main( int argc, char ** argv )
{

        KAboutData aboutData( "foo", "foo", "2" ,"foo" , 
KAboutData::License_GPL, "a");
        KCmdLineArgs::init( argc, argv, &aboutData );
        KApplication a( argc, argv );

        beIRC w;
        w.show();
        a.connect( &a, SIGNAL( lastWindowClosed() ), &a, SLOT( quit() ) );
        return a.exec();
}
