Try this:

#!/usr/bin/env python

import sys
from qt import *
            
class PyQMainWindow( QMainWindow ):
    def __init__( self, parent = None, name = None, fl = 0 ):
        QMainWindow.__init__( self, parent, name, fl )
        self.setCaption( self.tr ('Traceback Test') )
        buttonGroup = QButtonGroup( self.tr ('Traceback Test'), self,
'group' )

        global multiLineEdit
        multiLineEdit = QMultiLineEdit( buttonGroup, 'edit' )
        multiLineEdit.insertLine ( "In PyQApplication.exec_loop()..." )
        
        badButton = QPushButton( self.tr ('&Error'), buttonGroup, 'bad'
)
        quitButton = QPushButton( self.tr ('&Quit'), buttonGroup, 'quit'
)

        vBoxLayout = QVBoxLayout( buttonGroup )
        vBoxLayout.addWidget( multiLineEdit )
        vBoxLayout.addWidget( badButton )
        vBoxLayout.addWidget( quitButton )
        
        self.connect( badButton, SIGNAL ('clicked()'), badFunc )
        self.connect( quitButton, SIGNAL ('clicked()'), self, SLOT
('close()') )
        self.setCentralWidget( buttonGroup )

def badFunc():
    try:
        assert bob, 'NameError'
    except NameError, args:
        lines = '%s: %s' % ( args.__class__.__name__, args )
        multiLineEdit.insertLine( lines )

def main( *args ):
    app = QApplication( *args )
    win = PyQMainWindow( None, 'main', Qt.WDestructiveClose )
    win.resize( 300, 50 )
    app.setMainWidget( win )
    win.show()
    app.connect( app, SIGNAL ('lastWindowClosed()'),
                       app, SLOT ('quit()') )
    app.exec_loop()

if __name__ == "__main__":
    main( sys.argv )
