>>> import numpy
>>> numpy.__version__
'1.5.1'
>>> class X:
...     pass
...
>>> numpy.asarray([X(), numpy.asarray([1, 1])]).shape
(2,)
>>> numpy.asarray([numpy.asarray([1, 1]), X()]).shape
()
>>>

I would expect (2,) in the second case too.  The following works ok:

>>> numpy.asarray([1, X()]).shape
(2,)
>>> numpy.asarray([X(), 1]).shape
(2,)
