I do, but I've had that enabled for at least the last 6 months.  I
went away on vacation, re-pulled & re-built, and got the inotify
errors. Relevant .emacs:

 '(dired-auto-revert-buffer (quote dired-directory-changed-p))
 '(global-auto-revert-mode t)
 '(global-auto-revert-non-file-buffers t)

although disabling those 3 makes no difference to the behaviour.

I've double checked my emacs build was using gnotify before.

It's always possible that inotify is trying to access some
non-existent file, but without a filename that's hard to determine.
