AJAX menu conflicts with Theme developer module (from devel)

I setup a minimal drupal 6.2 test site with jstools and active menus and german locale. The collapsing and expanding of menus works as long as no AJAX loading is required. Here is an example POST-Request/Response from firebug for the menu admin/build invoked from admin.

Location with parameters:

http://drupaltest.localhost/activemenu/menu?path=admin/build

It looks like the first level of menu items is returned instead of the path specific sub menu items.
