If a user's talk-page is altered, the 'newtalk' flag is set, prompting the system to
display the "new messages" banner until the user clicks on the link.

In the event that the alteration was vandalism and the entire talk-page is deleted (for
example if the *only* edit is the vandalism) the 'newtalk' flag is not reset. When the user
responds the result is an error.

The deletion process should check if the page in question is a user's talk-page and if so
reset the 'newtalk' flag.
