    Henrique, this looks exactly the same as the error I got a few weeks
    ago. (See Migrations NPE 25/08/2008).

    It has to do with ERPrototypes and/or other models being within a jar.
    I submitted a patch for this (see thread 'erprototypes ... is not a
    File error') which I think Mike committed already. Are you using the
    latest nightly?
