Blendfile dont exist?

Hello. I have some nasty thing happen to my Blender 2.67 and my iMac 10.8.3

http://www.pasteall.org/blend/21702

For years I don’t have any problem with Save as ( Example Cartoon_blend )
At Finder - Blendfiles I keap my blendfiles more than 200.
1.
During the last 2 weeks my new blend files is not there inside the blend file. Why?

I have many times append stuff in to a new project from older blendfiles without any problem. Yesterday I try to append but nothing appear.

Is there maybe a bug inside Blender Cycle 2.67.

Can I create a project on Blender 2.67 Cycle and later on open up the file on Blender Cycle 2.66. (2.67 rendering for many days)

Thank in advance.
