Stefan,
You forgot the attachment.
dpi is an inherently confusing parameter because it can relate to font 
rendering and to the resolution of an image. So there are different 
kinds of dpi, but the distinction between them is not kept clear in the 
code--at least it wasn't the last time I looked into this, quite a long 
time ago.

I narrowed the problem down to this line:
matplotlib.rc('figure', dpi=300)
Does it do some magic behind the scenes?
Attached is the script that produces this:

I'm running 1.0.svn on OSX Snow Leopard, Python 2.6 and NumPy dev.
