Stefan correctly identified the problem.   The dimension-discovery code 
is getting confused.
This might actually be a fixable bug.  But, in general getting the 
N.array() code to correctly guess where the "Object-line" should be 
drawn is difficult at best.   The current code is a re-write of a 
previous code.  But, still it cannot solve the poorly defined problem.

So, I would suggest creating empty arrays and populating them...
