Doesn't work with custom post types

using this notation:

[catlist post_type=os_going_out name=”07-brunch” numberposts=5 excerpt=no thumbnail=no]

I have tried without the quotes too..

It doesn’t pick up the right posts.

I have the custom post type called “os_going_out”
and the slug of the taxonomy is called “07-brunch”
