"Advanced IMAP Controls" is a labs feature in GMail. Once you enable it there are some additional IMAP options. One of the options is that you can "hide" labels / folder from IMAP... In my case and, I think for many others using GMail IMAP with a desktop client, I had the "All Mail" folder hidden, because I don't want duplicates of my Inbox + my archive on my local computer... BIS 2.6 checks the "All Mail" folder for new messages to push to the device, so if you have it hidden, no soup for you.
