* When making a proxy, the lib linked IPO driver was also changed to point to the proxy object, and after undo this local proxy object was replaced so the pointer became invalid. In fact it is not needed at all to change this because the IPO code maps the pointer to the local proxy object already. * Undoing the make proxy operation would crash because the proxy_from pointer in the library linked object would still point to the removed object. Now it clears all these pointers before undo, because on each undo memory file read they will be set again anyway.
