Safari acting funny...weird Console entries...

Well just today I've noticed that when some pages load Safari will stop for a bit and display the spinning wheel of death and then continue to load the whole page...upon looking in the Console I see some worrisome entries which I've bolded below:

any ideas if any of these errors are bad and if so how do I fix 'em? Thanks!
