Comment:

 It seems you are using one or more of the `mce_buttons`, `mce_buttons_2`,
 `mce_buttons_3`, etc. filters. They pass an array and expect an array
 back. If you're returning anything else than array, you're using them
 improperly. Keep in mind that another plugin can be using the same filter
 after you and is expecting an array too.
