Is it usefull to know that you must do a new backup? There is nothing about solving the problem in Pondini's page, OR at Apple article HT4076. Solving the problem is something that Apple should address to, not me. I just want things to work and feel safe in recovering my files, including accidentally deleted data.
A year ago there were MANY of us with the same problem.... not just me and my two macs.
Btw, my permissions and disk are fine according to disk utility. They were fine a year ago as well.
