You mean "buffer-undo-list" not "buffer-undo-tree" right?
I checked Emacs 24.3 and as I suspected it's quite easy to make undo-tree-canary appear in the buffer-undo-list. What changed is the error checking in core Emacs. If you expected that undo-tree-canary would never be there between commands, that has not been so for some
time.
Could you tell me more about the purpose of undo-tree-canary?
