How to access sximporter? Urls issue.

I'm having troubles with getting into sximporter page at my local OSQA instance.

I started some debugging and found out that in fact import of an appropriate module didn't run.

In forum.urls there's a call to get_modules_script('urls') which tries to get a list of <forum_module>.urls scripts.

The body of get_modules_script function is following (as in trunk):

def get_modules_script(script_name):
    all = []

for m in MODULE_LIST:
        try:
            all.append(__import__('%s.%s' % (m.__name__, script_name), globals(), locals(), [m.__name__]))
        except ImportError, e:
            #print repr(type(e)) + m.__name__ + ":" + str(e)
            pass
        except:
            import traceback
            msg = "Error importing %s from module %s: \\n %s" % (
                script_name, m.__name__, traceback.format_exc()
            )
            logging.error(msg)

return all

In fact there is forum_modules.sximporter on the MODULE_LIST and whene it comes to import it with a call:

__import__('forum_modules.sximporter.urls', globals(), locals(), ['forum_modules.sximporter'])

I get the ImportError that "No module named urls" (i.e. facebookauth module does import without an error) and there is urls.py file under forum_modules/sximporter path.

Am I missing sth? Why it's not importing?
