[mod_python] SystemError: error return without exception set

Hi,

I'm trying to run moinmoin on mod_python 2.7.10, python 2.3.5, apache
1.3.36, on a NetBSD.  I get the error on the subject when it's running
the following code (in the line marked with "=>"):

        sys.stderr.write(str(env)+"\n")
        sys.stderr.write(env["HTTP_ACCEPT_LANGUAGE"]+"\n")
        sys.stderr.write(self.http_accept_language+"\n")
 =>     sys.stderr.write(env.get('HTTP_ACCEPT_LANGUAGE',self.http_accept_language))

(In fact the original code said the following:
        self.http_accept_language = env.get('HTTP_ACCEPT_LANGUAGE',
                                            self.http_accept_language)
 but I inserted the four lines before that to see what's in the
 variables.
)

The output in the log file is:
    {'UNIQUE_ID': 'RMThtFLFptoAAB6zB5o', 'SERVER_SOFTWARE': 'Apache/1.3.36 (Unix) mod_gzip/1.3.26.1a mod_python/2.7.10 Python/2.3.5', [...snip...] 'HTTP_ACCEPT_LANGUAGE': 'el,en-us;q=0.7,en;q=0.3', [...snip...] }
    el,en-us;q=0.7,en;q=0.3
    en
    [Mon Jul 24 17:05:24 2006] SystemError: error return without exception set

So, as I understand, env.get(...) should return "el,en-us;q=0.7,en;q=0.3".

You have any clue what to check next? Thanks!
