I guess that it took the whole of the rest as the title, since the title had not been closed. You would have seen the problem if you had copied the complete html of the page (View, Page Source or similar in the browser) and pasted it into the w3c htlm validator website. It would have told you about the error.

A good tip when something apparently very strange like this is happening is to look at the html source, you would then have seen that there was something there that should have been displayed but was not, this would have told you that it must be an error in the html rather than any subtle rails issue.
