[PySide] PySide crash on Vista

[anatoly techtonik]

Hello,

I am trying to port a big PyQt4 application to PySide, and I have face
many stacktraces, but now I've got a condition when PySide crashes
Python. Is this ok in PySide world? Shouldn't this condition be
intercepted and displayed as Python stacktrace? How can I quickly
debug why this happens?

This is a minimal example that causes crash with PySide 0.4.1
If you comment line ''self.light_mode = False' - this won't happen.
I do not remember any restriction that parent constructors must
be called first in Python. Can anybody explain?

from PySide.QtGui import QWidget, QApplication, QMainWindow

class ExternalConsole(QWidget):
def __init__(self, parent):
self.light_mode = False
QWidget.__init__(self, parent)

class MainWindow(QMainWindow):

def __init__(self):
super(MainWindow, self).__init__()
self.extconsole = ExternalConsole(self)

app = QApplication([])
main = MainWindow()
print "impossible"
main.show()
app.exec_()

This bugs was fixed on GIT mainline, check details on:
http://bugs.openbossa.org/show_bug.cgi?id=378

You can make this work in current release just changing the order of
you call the base constructor.

class ExternalConsole(QWidget):
def __init__(self, parent):

QWidget.__init__(self, parent)
self.light_mode = False # << put this after base constructor call

(sorry about the delay.)

We have had initial discussion about doing the next release in the
beginning of our next sprint. In practice, the source packages would be
available approximately two weeks from now.

Cheers,
