QWebview Crashes with a simple example

[Schizo]

I did install qt with pip install git+git://github.com/pyqt/python-qt5.git in my virtual Python 2.7 environment. However, running this simple QWebView Snippet causes a crash. Any Ideas?

from PyQt5.QtWebEngineWidgets import QWebEngineView as QWebView,QWebEnginePage as QWebPage

from PyQt5.QtWidgets import QApplication
from PyQt5.QtCore import QUrl
import sys

class View:
    def __init__(self):
       self.view = QWebView()
       self.view.load(QUrl("https://google.com"))
       self.view.show()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    view = View()

It's looking for qtwebengine_locales but can't find it. Further details, if I don't specify the plugin path's, I'm getting an error, that the qwindow module wasn't found, so I'm setting:

set QT_PLUGIN_PATH=D:/venvs/pyqt5Test/Lib/site-packages/PyQt5/plugins
set QT_QPA_PLATFORM_PLUGIN_PATH=D:/venvs/pyqt5Test/Lib/site-packages/PyQt5/plugins/platforms
