    Happens after clicking on edit when there is geometry already in the editor. Reproduced the problem without the tracebacks shown earlier.

  2. Juan Pablo Caram reporter

    The "edit geometry" button calls self.draw.edit_fcgeometry(self.collection.get_active()) which in turn calls self.connect_canvas_event_handlers(). So they get connected twice.
