If I execute the following code, I get the message:

QTextCursor::setPosition: Position '5' out of range

This is just a small example to reproduce the error message. Does any one now how to avoid this or why it happen?

from PyQt5 import QtWidgets 
import sys

class programm(QtWidgets.QMainWindow):

  def __init__(self):
    QtWidgets.QMainWindow.__init__(self)

  def message(self):
    dialog = QtWidgets.QMessageBox(self)
    dialog.setText('Test')
    dialog.setDetailedText('Test')
    dialog.setVisible(True)

app = QtWidgets.QApplication(sys.argv)
prog = programm()
prog.show()
prog.message()
sys.exit(app.exec_())

Did you use Qt Designer for the original code? – ham-sandwich Sep 15 '14 at 15:39
@ham-sandwich: No, I didn't. – DerJFK Sep 15 '14 at 15:41
Does the code otherwise work? You may find this is a problem with your window manager rather than pyqt5. – mdurant Sep 15 '14 at 17:35
Obviously a Qt bug of some kind (there are lots of similar reports if you do a web-search on the error message). I can't reproduce it on Linux using qt 5.3.1 and pyqt 5.3.2. What's your setup? – ekhumoro Sep 15 '14 at 17:38
I use qt 5.3.1 and pyqt 5.3.1. The message just seems to be a warning, the rest of the code is working fine. – DerJFK Sep 15 '14 at 19:08
Have you tried keeping a reference to dialog, e.g. self.dialog = QtW.... – bootchk Sep 17 '14 at 14:36

It's a Qt's problem, not python's or smth else's. Sometimes Qt screws up :) – mlvljr Oct 31 '14 at 00:44
