Console logs HELP

[jon08]

I'm running a clean install of Snow Leopard 10.6.2 and when checking Console I constantly see such error msgs:

Nov 22 18:04:01 my-name-MacBook-Pro com.apple.Dock.agent[83]: Sun Nov 22 18:04:01 my-name-MacBook-Pro.local Dock[83] <Error>: kCGErrorIllegalArgument: CGSSetWindowTransformAtPlacement: Singular matrix [0.000 0.000 0.000 0.000]

Any idea what this is, and if it's normal to have it appear on the regular basis??

Ok so I just repaired permissions and verified disk, then restarted. When it rebooted I opened Console and then opened Safari. Safari was my only app open (ok, along with Meteorologist and Caffeine in menubar), and before long the "error" logs appeared again.

So apparently it has to do with Safari?? But what could be wrong?
