Question

I have a python script which I call using python main.py on my terminal. It starts a Qt-GUI which executes properly and terminates when I close the GUI.

However, sometimes the last debug message “over and out” is printed but the script itself does not terminate. Neither ctrl+c, ctrl+d nor ctrl+z have any impact on the execution. It seems to me as if this happens when an exception was thrown inside the program (and caught by the GUI).

I do not know how to debug this since it obviously does not happen in the GUI itself. How do I debug this and find out, what I did wrong?

if __name__ == '__main__':
    import sys 

    app = QApplication(sys.argv)
    form = MainGui()
    form.show()
    app.exec_()
    print "over and out"

EDIT: It seems to me as if there is some thread still being active in the end. However, I do not explicetely work with thread (I do not know what Qt does internally…). Is there a way to view all running threads in the end?

EDIT2: Oh my f*ing god. The solution simply was restarting my system. Somehow my OS did some crazy stuff and prevented the script from terminating.
