Blizzard conflict

[Spahut]

I'm getting the "Carbonite has been blocked from an action only available to the blizzard ui. You can disable this addon and reload the ui."

This was whilst doing quests in the pandaren starter area, when i click on an item in the quest list, this happens.

For instance the quest "Shu, the Spirit of Water", you get a "Sun Pearl" item in the quest list, when I click on it (on the Carbonite quest list) I get this dialog - this is out of battle.
