1. Go to http://demoauthor.magnolia.info/.magnolia/pages/adminCentral.html
2. Enter "superuser" for both username and password
3. Once page loads, click any of the navigation on the left side (Website, Documents, etc.)
Expected behavior: main section of page should load with appropriate content
Actual behavior: main section blanks out, but never loads with replacement content
This works correctly in the current release version of Safari
Confirmed with r26922.
bisect-builds tells me this regressed between r25552 and r25571.
Rolling out <http://trac.webkit.org/projects/webkit/changeset/25563> fixes this.
Works for me with WebKit nightly r35289.
