The crash happens in the method CmdPartDesignMoveFeature::activated on line 636:

    App::DocumentObject * sourceNewTip = source->Tip.getValue();
>  doCommand(Gui,"Gui.activeDocument().show(\"%s\")", sourceNewTip->getNameInDocument());
because 'sourceNewTip ' is a nullptr. Btw, to me this block doesn't make much sense anyway because in line 619 the Tip is removed from 'source' but nothing has been added to it. So, why is there a second call to get its Tip (when it actually must be null).

The code can be easily fixed by adding

    App::DocumentObject * sourceNewTip = source->Tip.getValue();
    if (sourceNewTip)
        doCommand(Gui,"Gui.activeDocument().show(\"%s\")", sourceNewTip->getNameInDocument());
but when trying the example with the three bodies and a box, the box will be moved but not its attached coordinate system. So, to me it seems more things are broken in this command (or I don't understand the logic :) ).

This can not be reproduced anymore. I guess Werner fixed it in the meantime.

I think this ticket should be closed.
