Copying layouts with vla-CopyObjects breaks drawing

[buntobaggins]

I am currently writing a program that will take layouts defined in a template file and copy them over to the current drawing. But running this program will cause the the file to break. The new layouts will not show up and if you attempt to switch to a different layout AutoCad will crash. If you try to open the file up again AutoCad will say its corrupted and will repair the file which seems to fix the problem. 

(defun c:copyLayouts ()
	(vl-load-com)
	(setq acadObj (vlax-get-acad-object))
	(setq doc (vla-get-ActiveDocument acadObj))

  	(setq impdwg (getfiled "Select Master Template" "" "dwt" 16))
  	(setq impdoc
	        (vla-getinterfaceobject
		(vlax-get-acad-object)
		(strcat "ObjectDBX.AxDbDocument." (itoa (atoi (getvar 'acadver))))
		);vla-getinterfaceobject
	);setq
  
  	(vl-catch-all-apply 'vla-open (list impdoc impdwg))
  
  	(setq layoat (vlax-get-property impdoc 'layouts))

	(setq safeLayout (vlax-make-safearray vlax-vbObject (cons 0 (- (vla-get-count layoat) 1))))
  
  	(setq i 0)
	(repeat (vla-get-count layoat)
		(vlax-safearray-put-element safeLayout i (vla-item layoat i))
		(setq i (1+ i))
	);repeat

  	(vla-CopyObjects impdoc safeLayout (vlax-get-property doc 'layouts))

  	(princ "\n\ncopy done\n\n")
  	(princ)
);defun

 

This only seems to be a problem with layouts. Using the same code for say a UCS works just fine. This is probably just some stupid mistake but I have been stuck on this for a while now so any help would be appreciated.
