Well now this is somewhat frustrating.

This was a valid package containing high-quality metadata.

Why has this package been deleted? By whom? Could someone with the  
required privileges (what privileges are required and who has them?)  
please check this?

Is this maybe another instance of this one?

It appears that the web front-end was implemented using the same  
logic: When I go to http://ckan.net/package/bibbase, then it redirects  
me to my user page (I am already logged in). I suppose the idea is  
that a user might possibly have another set of credentials with  
different permissions?

No, this behaviour is not helpful.
