It's not documented, but Topic regexps are compiled in VERBOSE mode
which means that unescaped whitespace outside of character classes is
ignored. This and other issues with Topic regexps are fixed for
Mailman 2.2, but for now, you need your regexp to be

^(Re:\ \[Rappnet\]\ )?Loc(al)?[:.]

however you will still have issues with subjects like

Re: Re: [Rappnet] Local: something

Re: Fwd: [Rappnet] Local: something

Re(2): [Rappnet] Local: something

and so forth.
