adict uses an idle timer so look at `timer-idle-list' instead of `timer-list'.

I use this code to treat the symptom:

    (eval-after-load 'auto-dictionary
      '(add-hook 'kill-buffer-hook
                 (defun cofi/maybe-cancel-adict-timer ()
                   (when adict-timer
                     (cancel-timer adict-timer)))))

But the problem is - for me at least - a pretty new one, meaning
some change in emacs caused this (adict hasn't changed for years).

As adict itself clears the timer when `auto-dictionary-mode' is disabled
I'd guess that modes don't get disabled anymore when a buffer is killed.
