Dear Mike, dear list,

thanks for the continued help!
Here are my 'news':

Just now I couldn't reproduce this. However, the fonts in the png and 
eps are quite different.

When I run my dea.py with the attached matplotlibrc, then I get both a 
png and an eps, however, the Chinese is still not rendered (see attachments)

I noticed the following in the ~rc:
cairo.format      : png      # png, ps, pdf, svg

But having it in or out makes no difference.

I changed this now.

python-cairo: 1.8.6-1ubuntu1

In [15]: cairo.version
Out[15]: '1.8.6'


I wasn't able to find pycairo on my system (even after installing 
python-cairo-dev). I belive pycairo and python-cairo are in fact the 
same thing.

Google found this:

"Just for your info if your interested in programming with cairo on 
ubuntu. I wanted to add svg, ps and pdf support to cairo (the ubuntu 
packages don't support these cairo render backends yet.)"
https://wiki.ubuntu.com/CairoPythonUbuntu

Could this be the reason for my troubles (under Ubuntu)?

I changed the = for a colon, yielding a nasty message:

david@ubuntu:~/Documents/PhD/Dissertation/LaTeX/figures$ python dea.py
/usr/lib/pymodules/python2.6/matplotlib/__init__.py:653: UserWarning: 
Duplicate key in file "/etc/matplotlibrc", line #329
   warnings.warn('Duplicate key in file "%s", line #%d'%(fname,cnt))

Hopefully we will get to the bottom of this! I am sorry to bother you 
with all this -- and appreciate your efforts!

Greeting from Beijing,
