help - Kernel panics frequent

Thanks for attempting to answer my plea - this is my first month on the mac and I love it, but - I've started getting FREQUENT KERNEL PANICS - and it worries me. It pops up with a power button picture, the screen goes darker, and it has a bunch of stuff in lots of languages. Then I have to restart! Is this normal for macs? Or macbooks? I copied some code sent to Apple if any of you can make anything of it:

If it helps, these things usually happen in Safari. I don't use parental controls (well I use k9, i think it said bluecoat in there), and I don't *think* I have any weird haxies.... other than like the dock, safari plugins, finder quit, etc. If you can help a stupid n00b out of the kindess of your heart, it would be appreciated.

Thanks in advance,

????? But, I think they stopped. I looked at the Troubleshooting Software guide and repaired disk permissions. There was a list of like 10 important things that were changed without the system or whatever..... It's all good, though! I hope K9 fixes the problem soon! Thanks for your help - I dunno how to close this thread (is that what I do?) but I guess more answers would still be helpful.

Thanks so much guys!
