I am a theme developer, and I have run into some problems with custom post types / taxonimies and nav-menu lately.
For some reason, the taxonomies do not show up in the nav-menu panel, even though there has been created terms and posts have been added.
This only happens on some installations. On my testinstallations on wp3.1 and on Mu 3.0, everything works fine.
Has anyone else run into this problem, and managed to solve it?
