Yeah, I think it's an issue in outline (that should be fixed).

As previously discussed in some other bug report *vague hand wave*, it
makes no sense to use regexps for outline in generated buffers.  The
functions that generate the buffers knows what's a heading, and should
mark the headings properly (with text properties), and
outline-minor-mode should just react to these text properties in these
buffers.
