I am getting this error when trying to add a menu block with my Slate theme:

warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'slate_admin_block_content' was given in /Applications/MAMP/htdocs/Springfree/includes/theme.inc on line 656.

Any help appreciated.

I've just had same problem, adding a new menu block. Same error (different path, obviously, but otherwise 100% identical). The menu items work and open correctly, but in a new & themeless page. Any ideas?

Slate is no longer included with the Admin module. See http://drupal.org/project/admin

So, I don't think there's anything to fix here. Likely it was a problem with that theme and not the module, but Dev Seed is no longer actively developing that theme.
