Thank you for the 'fix'. Both the demo and my old matplotlib based scripts work again.

in matplotlib/dates.py, change line 155 from
remainder = x - ix
remainder = float(x) - ix
The problem is that matplotlib uses numpy arrays for the xaxis. As you have a
64b system, the arrays are in float64scalars, that divmod doesn't know how to
process (unless you have a very recent of numpy). The trick above forces a
downcasting of float64scalar to float32scalar, divmod can now work.
