I'm having the same or similar error. Not really sure what can be done about it.

As you can see, mine is hanging on Ring Tones (or perhaps the item that comes just after ring tones and it trips up before the display can indicate what it is currently processing).
Not sure what the workaround or solution is. I'm going to upgrade to .168 and see if that makes any difference.
