I am using Django CMS 3, CKEditor 4.3 and I got the same problem using twitter bootstrap glyphicon. Looking at : http://ckeditor.com/forums/Support/Prevent-removal-of-empty-span-tags#forum-topic-top.

To allow empty span tag, I have added at the end of ckeditor/config.js

CKEDITOR.dtd.$removeEmpty.span = 0;
