It looks like a bug in Aperture
Just to be sure, there is a difference in what you see when you do this in a library logged in as yourself and when you do this in a library logged in as the Guest user?
If so then this can only be something in your environment, not an Aperture issue.
With the new OS getting rid of preferences can be a real problem. As a test now I just tried it and I had to reboot. Just logging off did not do it.
If after you have removed the preference file (com.apple.Aperture.plist) and the Aperture folder in the Containers folder when you log into Aperture you do not get the Welcome To Aperture splash screen then the preferences for Aperture have not been reset.
As I said to get this to happen for me I had to
- Quit Aperture
- delete the file and the folder
- Re-boot
Then I got the Welcome to Aperture splash screen.
So basically if the preferences have been remove when you start Aperture it should appear as if Aperture is running for the first time.

Don;t worry you can reconnect to your library by closing Aperture, finding your library in the Finder and double clicking it.
