Latest upgrade was 29th May. The upgrade prior to this was in the second half of April sometime.
However, I believe I have always had this error, except maybe after the very first update/upgrade, straight after installation (snapshot 23796, was bang up to date at the time).
I can't say for certain whether it's even causing any problems. One really annoying problem that I have is that my N800 orbiter will most of the time crap out when, and only when, I select TV. No other orbiter does this (my only other orbiters are Android touch orbiters or web orbiters). Could it be related? I returned to a backup image I made on 12th April specifically to find out where the problem was, and naturally I upgraded straight away because I was after new features, and still the orbiter exhibited this strange behavior. Perhaps I should go back to this image and not upgrade?
Cheers,
Matt.
