You have been subscribed to a public bug:
conftest.py created in sourcecode/mailman/configure.in gets passed a partial group name when the group name has a space, such as "domain users".
It appears to be passed at line 382 where it is assigned to mailmangroup and that MM_FIND_GROUP_NAME takes a list of space separated groups.
