I have a QMessageBox inside a Plugin which is simply called by
msgBox = QMessageBox() ret = msgBox.exec()
When I click the OK button there is a warning in the terminal:
Warning: QBackingStore::endPaint() called with active painter; did you forget to destroy it or call QPainter::end() on it?
After this warning algorithm works, everything is okay. However if I try multiple times to call QMessageBox and click OK the warning changes on:
Warning: QBasicTimer::stop: Failed. Possibly trying to stop from a different thread*.
In the end of the end QGIS died on signal 11[New LWP 148808]
