toplevel spaces page doesnt display

[JLuc]

On Firefox 30 on Ubuntu 13.10, on the http://rubydoc.info/gems/preflight/0.3.0/frames page, the "Top Level Namespace" link at the top of the left column loads a right frame that keeps looping with following message :

<<
Libraries » preflight (0.3.0)
Processing preflight
preflight (0.3.0) is being processed. You'll be redirected when the pages are built, it shouldn't take much longer.

and never displays its wanted content.

Other pages are OK.
