No clue why this happens, but I can tell you what happens and a guess what the problem is:

Magento is checking all registered RSS feeds for admin news (the annoying bar at the top XXX unread notifications ALERT!! NEW PATCH bla foo).

When magento checks the feeds, all new items are written to the adminnoticiation_inbox table.

When this happens the primary_key is not set, so I would assume:

While copying the database you dropped the AUTOINCREMENT
