error in ax.bar

Hello list,

with the latest version of svn the pylab.hist command doesn't work if I use
align='center'. The error is due to a problem in the ax.bar - function as you
can see in the example below.
Probably width should be an array and not a list if one want to build
width/2..
I'm not sure what is the right solution, but I have two proposals:
- change line 3187 to left = left - npy.asarray(width)/2.0
- uncomment lines 3123-3126 in axes.py, but I don't know what will be
destroyed by that

thanks in advance for any help, best regards
Matthias

example - code :

In [1]: from numpy import ones, arange
In [2]: from pylab import axes
In [3]: ax = axes()
In [4]: ax.bar(arange(10), ones(10), width=0.8, bottom=None, align='center')
