It is strange, the iterator will crash when we use nested array, you could use 
subscript as 
workaroud, like

for i in xrange(len(array))

The root cause is the iterator of JSArray return a temporary object. To fix it, 
I force the 
iterator::dereference method return value instead of reference to a temporary 
object. 

Please check out the source code from SVN after r201, and verify it, thanks
