Yes. The regexp that searches for completed tasks in org-habit is
hard-coded to look for a 'State "DONE"' string. When org-log-done is set
to note, however, the log entries begin with 'CLOSING NOTE'. (A related
problem here is that it assumes DONE is the only relevant todo keyword.)

One workaround is to add the property LOGGING and set its value to
lognoterepeat. This produces notes with timestamps in the following
format (compatible with org-habit):

  - State "DONE"       from "TODO"       [2011-01-01 Sat 21:11] \\
    5 miles.

Another workaround is to make the setting associated with 'done in
org-log-note-headings to the same as 'state. One quick way to do that is
by evaluating the following expression:

(setcdr (assoc 'done org-log-note-headings) (assoc 'state org-log-note-headings))

As an aside, it seems to me that the "CLOSING NOTE" format that results
when org-log-done is set to 'note is inconsistent with other logging
behavior. For instance, when a "@" is added in org-todo-keywords, the
note is entered with the state change string.

Best,
