I was having similar issues with FCs all over the place, specifically Framework and Facebook the most. The culprit seemed to be contacts syncing or gmail syncing. What fixed it for me was the following steps:
• Ensure your contacts are backed up to Google.
• Manually flash the latest MIUI ROM
• Clear data on: Calendar Storage, Contacts, Contacts Storage, Gmail, Google Calendar Sync, Google Contacts Sync, Google Services Framework, Market, and Talk
• Remove your Google account from Accounts and Sync
• Manually reflash the latest MIUI ROM
It had to resync everything, and it's almost like some db got corrupted somewhere and had to be rebuilt. Again, it will clear everything, but if you have it all backed up on Google, it should be OK.
Hope this is somewhat helpful.
