Every time I have the problem that if an event (like MouseMove oder LeftButtonDown) is handled by one of these widgets the whole app crashes without any information why.</div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: tahoma, 'new
york', times, serif; background-color: transparent; font-style: normal;">I know so far that it is definitely in combination with events that are handled by the widgets. Whenever I delete the observer for such an event the previously problematic action doesn't crash the app anymore.</div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: tahoma, 'new york', times, serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: tahoma, 'new york', times, serif; background-color: transparent; font-style: normal;">I am curious why this is only happening with PyQt and not with Tk as this are the samples I tried. Next I want to debug into this problem using either Visual Studio or gdb. Has anyone had such problems using widgets in these combinations? Is it only a problem with pythonxy as this is what I was using all the time.</div><div style="color: rgb(0, 0, 0); font-size: 13px;
