There are certain letters used before a colon that make an inter-wiki link or a special page. Like "Thread:" or "Special:", "ib:" might be a language or something.

The moving part has to with namespaces, it thinks you are trying to move and article to a different namespace like "category:" or "talk:"

might not be a solution to this.

edit, found a unicode colon to use
