This appears to be a C library/OS issue that has nothing to do with
Mailman. getgrgid(gid) should return a struct group for the group
whose ID is gid. This structure should contain the information which
is a representation of the fields in the /etc/groups record for that
gid. If gid is valid, the return from getgrgid(gid) should not be null.

Mailman only cares about getgrgid()->gr_name.
