I'm using Win7 Simplified Chinese, with GRASS 6.4.3RC4 installed. After
GRASS started successfully, it raises ParseError in xml.etree.ElementTree
module when I click any tool or menu in Layer Manager window. For Example,
if I click "Add vector map layer" tool, error messages below will display
in Command Console, and d.vect setting window can't open.

ParseError

Finally I find that the bug is in task.py file with lines 460-470.
{{{
enc = locale.getdefaultlocale()[1]
if enc and enc.lower() == 'cp932':
p = re.compile('encoding="' + enc + '"', re.IGNORECASE)
tree = etree.fromstring(p.sub('encoding="utf-8"',
get_interface_description(name).decode(enc).encode("utf-8")))
else:
tree = etree.fromstring(get_interface_description(name))
}}}
On my PC, enc is 'cp936', but the encoding of string returned by
get_interface_description(name) is 'gbk'. I replace first two sentences
with
{{{
enc = locale.encodings.aliases.aliases[locale.getdefaultlocale()[1]]
if enc and enc.lower() != 'utf-8':
}}}
.
It works fine on my PC. But I don't know whether it succeeds in other
conditions.
