Matplotlib 1.3.1: plot(matrix("1,2,3")) -> RuntimeError: maximum recursion depth exceeded

Question

I am working with python 2.7.5 using numpy.version: 1.7.1 matplotlib.version: 1.3.1 When I start "ipython2 --pylab" and execute the following code

x = matrix("1,2,3")
plot(x)

I get the error message

[...]
/usr/lib/python2.7/site-packages/matplotlib/units.pyc in get_converter(self, x)
    146             except AttributeError:
    147                 # not a masked_array
--> 148                 converter = self.get_converter(xravel[0])
    149                 return converter
    150 
/usr/lib/python2.7/site-packages/numpy/matrixlib/defmatrix.py in __getitem__(self, index)
    303 
    304         try:
--> 305             out = N.ndarray.__getitem__(self, index)
    306         finally:
    307             self._getitem = False
RuntimeError: maximum recursion depth exceeded

In the older matplotlib version 1.3.0 this error was not present.

Any help is highly appreciated! Thanx, Klaus.

Is there a handy guide on how to update to the master branch? I'm using Anaconda and it hasn't been updated yet as far as I can tell.
