CKEDITOR 4.1: When destroy() called, it throws an error.

Hi all,

This is the trimmed version of my code.

var foundEditor = CKEDITOR.instances[id];

if (foundEditor) {

    foundEditor.destroy();

}

And whenever destroy() called, this exception message will show up in my Chrome debug console:

Uncaught TypeError: Cannot call method 'getRanges' of null

Any ideas?
