PyQt5, Qt5.1.1, ASSERT failure in QVector

tuxerware

Hi! I'm experiencing a problem that might be a bug in PyQt. Example:

@class CommClient(QObject):

def init(self, parent=None):
QObject.init(self)
self._devicelist = "--"

self.timer = QTimer()
self.timer.timeout.connect(self.test)
self.timer.start(2000)

def setDeviceList( self, devlist ):
self._devicelist = devlist
self.deviceListUpdated.emit()

def getDevicelist(self):
return self._devicelist
deviceListUpdated = pyqtSignal()
devicelist = pyqtProperty(str, getDevicelist, notify=deviceListUpdated)

def test(self):
self._devicelist = "New Device"
self.deviceListUpdated.emit()
self.timer.stop()

app = QApplication(sys.argv)

qmlRegisterType(CommClient, 'SDL', 1, 0, 'CommClient')

view = QQuickView()
view.setWidth(500)
view.setHeight(500)
view.setTitle('CommClient')

view.setSource(QUrl('main.qml'))
view.show()
app.exec_()

@

And the qml file:

@import QtQuick 2.0
import SDL 1.0

Rectangle {
width: 400
height: 400

Text {
id: myText
text: commClient.devicelist
anchors.horizontalCenter: parent.horizontalCenter
}

CommClient {
    id: commClient
}

}@

When the time fires and the signal is emitted I get:

@
ASSERT failure in QVector<T>::at: "index out of range", file ../../include/QtCore/../../src/corelib/tools/qvector.h, line 350
Aborted
@

Does anyone have a clue if it's a bug in my code or perhaps PyQt?

I am running the latest snapshot of PyQt5.1 ( PyQt-gpl-5.1.1-snapshot-41b8f6ca2ea4. ) and stable Qt5.1.1 built from source on Ubuntu 12.04.
