I would be careful about auto-closing issues after a year. It's quite possible that some issues are genuine but for various reasons (time required, difficulty of the problem, etc...) people might not do anything about it right away. You can check the feature requests or bugs databases for large projects like Firefox or WebKit for example and find plenty of entries that are several years old yet those entries often still have comments being made which shows that at least some people care about them.
