On a recently installed (from internet via Recovery Disk) 10.7.4 Lion system the system.log is filled with multiple "com.apple.dock.extra: ... Could not connect the action buttonPressed: to target of class NSApplication" message.

Have tried creating a new account, with only 2 icons in Dock: Finder and Recycle bin, though that also generates these "com.apple.dock.extra: ... Could not connect the action buttonPressed: to target of class NSApplication" messages in system.log.

System.log excerpt:

Jun 24 16:14:50 mac03 com.apple.launchctl.Aqua[1209]: usage: launchctl load [-wF] [-D <user|local|network|system|all>] paths...

How can this behavior be "fixed"? The goal is to prevent these messages from appearing in system.log.

I get these as well, don't think they are a reason to worry. –  patrix Jun 24 '12 at 14:42

I don't worry, but would like to get rid of these messages. –  Pro Backup Jun 24 '12 at 14:49

You have a similar request to this question:

How to fix message spam from usbmuxd in console (_SendDetachNotification/_SendAttachNotification)

The answer I put there should work if this hasn't fixed itself via time or an upgrade to a newer OS. Just send the com.apple.dock.extra messages to /dev/null by editing /etc/syslog.conf
