New submission from Andreas Hasenkopf <webmas...@hasenkopf2000.net>:

I'm using 64bit Arch Linux and Python 2.7.2 compiled with GCC 4.6.1.

I have noticed in several ocassions that the interpreter is complaining about

AttributeError: XMLGenerator instance has no attribute '_write' (in case of 
module xml.sax.saxutils.XMLGenerator)

or

AttributeError: RendererGDK instance has no attribute '_text2path' (in case of 
matplotlib when trying to use TeX formatting of text)

When I have a look into the corresponding modules I can clearly see method 
definitions (e.g. def _write(self, text) in line 97 of xml/sax/saxutils.py

I have no clue, why it is happening in some modules, but not in others. If a 
write my own module containing a class with a _write method it is working fine.
If I write a class derived from xml.sax.saxutils.XMLGenerator and overwrite the 
_write method it is known to the system, but many of the attributes beginning 
with an underscore appear still to be unknown...

This is very odd?!
