Whenever I stop a PLC simulation in the python3-dev branch, I get the mentioned error and the simulator doesn't show stopped ...
Starting the Simulator seems good ...

I stop it and ...
The console shows this output ...

Latest build does not match with connected target.
PLC data transfered successfully.

(service.py:13335): Gtk-CRITICAL **: 08:46:24.788: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed

and started again ...

With console output ...

I think it is actually working but the GTK tie in for the GUI is not quite right in this case. So this is not a critical bug IMHO.

I think this is a duplicate of issue #56
