I think I've seen where and how the problem occurs and am
currently testing an easy patch.

That will however give an error message for all calls 
   options( mylist )
when mylist is a list that has  
  length(names(mylist)) !=  length(mylist)

You weren't making a "feature request" in the other direction 
where you?
