works for me (on fedora, using a fresh build).

$ ./python
Python 2.3.4 (#1, Sep 20 2004, 12:46:02)
>>> from elementtree.ElementTree import Element, SubElement, dump
>>> elem = Element("window")
>>> dump(elem)
<window />
>>> from elementtree.ElementTree import VERSION
>>> VERSION
'1.2'

$ ./python elementtree-example-1.py
<window />

note that the error occurs in the regular expression compiler.  my guess is that
you've accidentally modified the ElementPath file in some strange way.  here's
what the offending pattern looks like on my machine:

xpath_tokenizer = re.compile(
    "(::|\.\.|\(\)|[/.*:\[\]\(\)@=])|((?:\{[^}]+\})?[^/:\[\]\(\)@=\s]+)|\s+"
    ).findall

does the elementtree selftest.py script work on your machine (you should get
a deprecation warning followed by "246 tests ok").
