I believe I've found a (temporary) fix in this forum thread:
http://www.castlecops.com/p984588-HTTP_Error_400_when_using_gknujon.html

Pasted here for posterity;

Edit the libgmail.py file.

In the function

def login(self)


change the following text:
Code:
try:
    link = re.search(RE_PAGE_REDIRECT, pageData).group(1)
    redirectURL = urllib.unquote(link)


to add the extra line:
Code:
try:
    link = re.search(RE_PAGE_REDIRECT, pageData).group(1)
    redirectURL = urllib.unquote(link)
    redirectURL = redirectURL.replace('\\x26','&')

Must have been some small change in gmail's redirect that put it off.
