This seems to have something to do with the caching in
Text._get_layout_super(). The first script below works right, the
second has the exponents all wrong.

------------------------------------------------------------------------
#!/usr/bin/env python

import matplotlib
matplotlib.use('pdf')
from matplotlib import pylab

pylab.plot([0.001, 1, 10, 100, 1000])
pylab.gca().set_yscale('log')
pylab.savefig('foo1.pdf')
------------------------------------------------------------------------
#!/usr/bin/env python

import matplotlib
matplotlib.use('agg')
from matplotlib import pylab

pylab.plot([0.001, 1, 10, 100, 1000])
pylab.gca().set_yscale('log')
pylab.savefig('foo2.pdf')
------------------------------------------------------------------------

For some reason this doesn't happen with the eps backend, even though
it has flipy() == False, like pdf and unlike agg. Is there something
the pdf backend should do to reset the state of other objects when
switching to pdf from another backend?

Fixed in svn.
