I had the same problem and tried to find out if it was an extension that caused it, so I renamed my extensions folder and restarted, no more errors. Decided to add them back a couple at a time to find where it would break, added them all back...still no errors.

If anyone smarter than me want to figure out why, here is a list of the extensions I have:
