I don't see much resemblance to that example; and I haven't tried that 
example, but I did verify that the examples/annotation_demo.py in svn 
works as expected.

Time for bed, rest those bleary eyes...

The signature of the Annotation.__init__ does not match what you were 
trying to feed it.  Here is a modification that does match, but that may 
not be anything like what you were trying to do:

import pylab
import matplotlib as mpl
test = pylab.figure()
test_ax = test.gca()
test_ax.plot([1,2,3])

a = mpl.text.Annotation(

'F: a figure title (points)',
(-10, -10),
xycoords='figure points',
horizontalalignment='right',
verticalalignment='top',
fontsize=20)

test_ax.add_artist(a)
test.savefig('temp.eps')
