I got exactly the same problem.

Tried various things to avoid it( uninstal/instal with all ext on; uninstall/install wit all ext off...etc)

nothing helped...
I used to run it without any problems (os 9.2.1)untill I reformated my hd and updated to 9.2.2.

I will try to get help from Apple forum.

will post when find solution.

Do the same plz.

good luck
