but that bug is private?
I am getting:
" You are not authorized to access bug #215793"
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=215793

this is my second bug hit that is marked privated,
sadly related to cluster stuff
this is just a new trend in the working flow in redhat
or it is just because the reporter marked as privated
and redhat engineer respect the client's privacy ?

:-( I really do not like security by obscurity :-(
