All files are deleted from the local synced directories if, during a sync, MySQL is stopped:
http://bugs.owncloud.org/thebuggenie/owncloud/issues/oc-2085

Reproduction steps:
  1. Have an active sync running on a client
  2. Shutdown My SQL server but leave ownCloud server (i.e. apache) running
  3. wait a few minutes and watch files get deleted from the client.

HTTP creds: Fix GUI blocking for 5 seconds when entering wrong password
868d4c7 
The Qt HTTP thread calls authenticationRequired (indirectly) using a
BlockingQueuedConnection. So when we call invalidateToken from slot
connected to this signal and end up calling QNAM::clearAccessCache which
waits on the thread for 5 seconds

Backtraces:
