non obvious warning on configuration formatting issue

[Sebastien Bacher]

Binary package hint: bzr-builddeb

the default.conf for a sponsoring request has "[BUILDDEB" (lacking the ]) which leads to an non very obvious error when running bzr-buildpackage

"Building using working tree
bzr: ERROR: bzrlib.util.configobj.configobj.ParseError: Invalid line at line "1".
