[Q] Gmail - Out of date sync that won't update topic

I'm on CM 4.4.2 and I've had this issue a few times now. My Google account syncs properly except for Gmail which is "stuck" in an out of date sync. No matter what I do, Gmail refuses to update itself. This results in not getting new mail notifications, and not being able to see any new email since the last sync.

Things I've tried:

• Rebooting
  Clearing Gmail cache
  Clearing Gmail app data + cache
  Forcing a resync in Settings > accounts

This is what it looks like, you can see here 1 minute before the screenshot I forced a resync of my Google account, everything updates fine except for Gmail which is stuck on 2014-01-20.



After clearing app data + cache, Gmail is stuck on this screen:



The only way to workaround the issue is to remove my entire Google account and set it back up again on the device. This is not ideal, and the issue comes back at some point again.
