Luiz,

Attached is a patch metze provided that should fix this.

I attempted to validate this earlier, but ran into other issues with
FreeBSD and our make test environment, so I don't think proceeded. 

If you can validate the patch, I think we get get it into the RC
releases.  

Note that per the release notes we still have an outstanding issue with
FreeBSD rejecting lookup of names containing _.  

We don't currently have a workaround for this platform limitation.
