FAILED Builds RSS Feed Throws 'Internal Server Error' Instead of 'Access Denied' for Plan I Have No Permissions To

For Plan FOO, as User2 I have no permissions on the Plan. If I try to view the FAILED BUILDS RSS URL such as :

/rss/createAllBuildsRssFeed.action?feedType=rssAll&buildKey=PROJKEY-PLANKEY

It throws an Internal Server Error with Stacktrace :

Stack Trace:

javax.servlet.ServletException: Unable to find feed for this action

Instead I would expect the standard "Access Denied" page you get when you try to access a Plan or page you do not have permissions to.
