The new patch today seems to have broken the add-on or one of the libraries it uses. It doesn't load when visiting the mailbox, and there's a LUA error which I've included below:

LibQTip is a third party addon. I have repackaged it with the new toc and new dependencies will be uses which should fix the issue.
