Description Christopher Bruns 2010-09-30 17:53:40 EEST 
I encountered a python crash with a standard Python 2.6 install on a Mac Pro
with Mac OS 10.6.4 (Snow Leopard).  The crash occurs when I run the following
simple example program from the PyQt tutorial at 
   http://zetcode.com/tutorials/pyqt4/firstprograms/

The example program closes gracefully when I use PyQt4 instead of PySide.

Run the program and click the "Close" button to experience the crash.

############## begin test program ########################

#! /usr/bin/python

import sys

# Using PySide rather than PyQt4 causes crash on Mac on Close
# from PyQt4 import QtCore
# from PyQt4 import QtGui
from PySide import QtCore
from PySide import QtGui

class QuitButton(QtGui.QWidget):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.setGeometry(300, 300, 250, 150)
        self.setWindowTitle('Quit button')
        quit = QtGui.QPushButton('Close', self)
        # quit.setGeometry(10, 10, 60, 35)
        # quit.clicked.connect(QtGui.qApp.quit) # New way cmb
        self.connect(quit, QtCore.SIGNAL('clicked()'),
                     QtGui.qApp, QtCore.SLOT('quit()'))

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    qb = QuitButton()
    qb.show()
    sys.exit(app.exec_())

############ end test program #######################


The OS produced the following crash report:

Comment 1 Hugo Parente Lima 2010-09-30 18:34:55 EEST 
Maybe this bug is a duplicate of bug#388

Unfortunately we don't have a Mac to test it right now.
Comment 2 Christopher Bruns 2010-10-01 09:36:48 EEST 
Perhaps this is not exactly the same bug as bug#388, because on my Mac the
example program from bug#388 runs just fine, but my example program here
crashes, only when the "Close" QButton widged is clicked.
Comment 3 renato filho 2010-10-01 11:32:35 EEST 
The bug #388 does not fail in all linux distribution, I do not know what is the
exactly the reason but this happen when you are using KDE and PySide, then the
test can runs fine on your computer, I think the best way is apply the patch
used to fix bug and run against your test.
