OS X Mavericks lost my mail folders! After loading Mavericks it appears one of my mail folders, a key folder holding tax data has become completely borked.  As you can see from the attached image I have duplicate home folders.  I have already tried to rebuild this folder with no luck.  Any other ideas?

Rule of thumb, use Time Capsule = Problem Solved.
