Summary	0001428: Undo on FeaturePython causes crash
Description	I haven't yet found a way to reproduce this. It happens when a FeaturePython is going to be restores using the undo function in the GUI. The Object was a OpenSCADFeatures.RefineFeature. As far as i understand the stacktrace the following python code (of the viewProvider) caused the problem if hasattr(self.Object.Proxy,"Base"): objs.append(self.Object.Proxy.Base)
