Quick View's logs

I’m running OS X 10.6.8 and I’ve noticed that Quick View log something every minute!
Is it normal ? Shall I change the interval of time ? How ? I wasn’t able to find out any setting nor plist file to change that…

Just to give you some snapshots:
Schermata 2013-01-11 a 19.54.01.png

And, sometimes, it logs something like a JSON/key-value file with some data:
Schermata 2013-01-11 a 19.55.16.png
etc, etc…

I’ve also noticed the “firmware_update” recurrent page, but the automatic updates are disabled…

Don’t now if its normal, but I would call tech support on this one.
