Laden Sie eine einfache Qt-Designer-form in Pyside

Ich Sie ein einfaches Formular erstellen in Qt designer und versuche zu laden, es in eine Qt-Anwendung, die ich bin mit PySide, aber ohne viel Glück.

Hier der generierte code von "pyside-uic':

        self.nameLabel.setText(QtGui.QApplication.translate("clientEditorForm", "Name", None, QtGui.QApplication.UnicodeUTF8))
        self.profileButton.setText(QtGui.QApplication.translate("clientEditorForm", "Profile", None, QtGui.QApplication.UnicodeUTF8))

        self.applyButton.setText(QtGui.QApplication.translate("clientEditorForm", "Apply", None, QtGui.QApplication.UnicodeUTF8))

Dann meine einfach in der Anwendung:

import sys
from PySide import QtCore, QtGui

from clientEditorForm import Ui_clientEditorForm

class MyMainWindow(QtGui.QMainWindow):
    def __init__(self, parent=None):
        super(MyMainWindow, self).__init__(parent)
        self.ui = Ui_clientEditorForm()
        self.ui.setupUi(self)

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

Jedoch, wenn ich versuche es zu starten, bekomme ich die folgende:

QLayout: Attempting to add QLayout "" to QMainWindow "clientEditorForm", which already has a layout

und ein "segmentation fault". Ich bin Sie die folgenden grundlegenden Anweisungen in dieses tutorial aber ich kann nicht sagen, was ich falsch mache.

Stellt sich heraus, es ist ein Fehler in PySide mit der QSpacerItem Klasse. Auskommentieren der QSpacerItem Instanzen im code oben macht es nur gut funktionieren. Es gibt einen bug-report auf der PySide bugzilla.

Erstens sind Sie mit PySide(Nokia) nicht PyQt4(Riverbank Computing), obwohl Ihre API ist nahezu identisch, Sie sind nicht das gleiche Projekt. Die PySide Beispiele sind hier verfügbar:
git clone git://gitorious.org/pyside/pyside-Beispiele.git

Ich denke, das problem kann zu tun haben mit dem call of

super(MyMainWindow, self).__init__(parent)

versuchen

QtGui.QMainWindow.__init__(self, parent)

statt.

Ich weiß, es scheint wie es ist die gleiche Sache, aber ich habe lief in ähnliche Probleme mit super mit PyQt4, und von was ich kann sagen, Nokia PySide hat die gleichen Schwierigkeiten. Es hat etwas zu tun mit dem Wetter, den Python besitzt den Eltern oder es ist im Besitz von einem zugrunde liegenden C++ - Objekt. Zumindest versuchen Sie es, es dauert weniger als 5 Sekunden!

Unten ist das Beispiel, das ich bin stützen dies aus, es ist aus dem git repo für PySide.
