You check 'newvalues' for the 'title' property in an auditor and search
for this title in the existing issues, e.g.

new_title = newvalues.get ('title')
if new_title is None:
    return
for id in db.issue.filter (None, dict (title = new_title)):
    t = db.issue.get (id, 'title')
    if t == new_title:
        raise...

Note that since filter can only search for substrings you have to
compare all found issues for an exact match. There currently is no way
(except by resorting to sql) to search for exact matches. In one of the
latest patches the search has also been made case-insensistive for all
the sql backends.

You would have to register this auditor for the 'set' and 'create'
actions.

(I don't know if it's a good idea to not allow duplicate titles in
issues)
