ReferenceError: QTags is not defined

Hello,

I have this javascript error and it happens on custom post type edit page when there’s no editor.

I suggest that you check for QTags variable existence before you use QTags.addButton.

The code that causes this issue is in quicktag_buttons function.

Regards.
