[mod_python] "Method Not Implemented" on AJAX POST

Sorry if this is a repeat; I tried to send email earlier without actually
being subscribed and didn't see it on the archive.

Don't know if anyone else has run across this, but I've been getting "501
Method Not Implemented" when making AJAX calls on my mod_python site. This
has mainly happened when using Firefox 3 or the newest version of
prototype (JavaScript library).

I narrowed it down to the Content-Type of the request containing the
charset. For example, "Content-type: application/x-www-form-urlencoded;
charset=utf-8" rather than just "Content-type:
application/x-www-form-urlencoded."

I'm running mod_python 3.1.4 (on OpenHosting, if that helps explain my
setup). I was able to fix the problem by changing line 112 in
mod_python/util.py from:

if ctype == "application/x-www-form-urlencoded":

to

if ctype.startswith("application/x-www-form-urlencoded"):

Has this been already fixed in a later version of mod_python? If not, I
figured it might be a good idea to post my fix.
