I started experiencing FCs today and wondered what app I froze, using Titanium Backup Pro, that was causing the issue. At the bottom of the list was the two Yahoo! apps. I unfroze them and BAM!!! All better! 
Do NOT freeze Yahoo! Mail Authenticator. You will start getting 'Contact Storage' Force Closes.
FWIW, I do have 'Yahoo Contacts' frozen though, and no issues.
