[PyQt] Segmentation fault when running PyQt5 scripts through ipython

It works from plain python, or if I run it only once, since then I exit the process cleanly. I just did not expect it to cause segmentation fault. I would have expected a nice error message if the init cannot be run again. And the funny thing is that a similar program written with PyQt4 works.

Does ipython run the scripts in the same process?
If so that will not work for a Qt program as you can only init Qt once.
Run your code from normal python instead.

Hi,
I've tried to run a script containing pyqt5 code through ipython3 with `run -i simple.py`. First time it goes through without problems, but if I run it again it yields a segmentation fault.
I would appreciate any help.

Here is the script:
import sys
from PyQt5.QtWidgets import QWidget, QPushButton, QApplication
from PyQt5.QtCore import QCoreApplication
class Example(QWidget):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
self.show()
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
I've run it through gdb, and here is the result:
