hi guys,
I have a problem with the QLinearGradient(or even QGradient..).
Im trying to set another stops list to the gradient, but it produce a
segmentation fault.
Is it a bug or did I do something wrong ?
Note that Im using PyQt 4.2 with python 2.4.3 but I cant upgrade to
newer versions as we are currently in production...
Cheers
Laurent

painter = QPainter(self)
painter.setBrush(QBrush(self.gradient))
painter.fillRect(0, 0, self.width(), self.height())

app = QApplication(sys.argv)
widget = PyTest()
widget.show()
sys.exit(app.exec_())
