the error reported is actually in the error handling code; it indicates that the 
original error happened even before the _cellvalues were set up. We tried to fix 
these problems recently and the current code contains these lines in the 
identity method.

	nr = getattr(self,'_nrows','unknown')
	nc = getattr(self,'_ncols','unknown')
	cv = getattr(self,'_cellvalues',None)

ie we try to get reasonable values for these even when unset.
