axes.set_xticklabels bug?

simple pylab script: a = axes() a.set_xticklabels(['a',

    > 'b', 'c']) show()

    > When I move the mouse around the axes I get this error
    > from the callback:

    > .......
    > /usr/local/lib/python2.4/site-packages/matplotlib/ticker.py
    > in __call__(self, x, pos) 176 'Return the format for tick
    > val x at position pos' 177 if pos>=len(self.seq): return
    > ''
    --> 178 else: return self.seq[pos]
    > 179 180 class FuncFormatter(Formatter):

    > TypeError: list indices must be integers

    > "pos" is None

Did someone fix this? I can't replicate it.
