The problem is that User#notified_projects_ids= source:/trunk/app/models/user.rb@13435#L355 may receive an array of strings, for example from an update through a web form, which is stored as is. source:/trunk/app/views/users/_mail_notifications.html.erb@13435#L16 on the other hand expects an array of integers to populate the form.

The attached patch makes sure anything passed to User#notified_projects_ids= is stored as an array of integers in the instance variable.
