 Hi,

 I found this bug on mac os 10.5, with power pc and also on an intel
 computer (but not on a 64bit linux). I used numpy 1.1.1, 1.2, and the
 latest svn.

 In [6]: np.dot(np.array([]).reshape(1,0), np.array([]).reshape(0,1))
 Out[6]: array([[ 4.00002862]])

 In [7]: np.dot(np.array([]).reshape(2,0), np.array([]).reshape(0,3))
 Out[7]:
 array([[ 0.,  0.,  0.],
        [ 0.,  0.,  0.]])

 Thanks!
 Pierre
