Visiting revisions should try to update revisions before issuing a 404
I just visited http://mysite.com/projects/xxxx/repository/revisions/a1d98298d2c7bc8d0533b299c418526b8a11d85a and got an immediate 404. Then I visited http://mysite.com/projects/xxxx/repository and there was a long delay before anything was shown, but afterwards, the original link worked.
BTW, the long delay makes me wonder: are we expected to set up a cron job to update revisions? If so, that's not really clear from the docs.
