Network Pane causes System Preference to Crash

Question

An unusual problem has cropped up on my Black Macbook 2 GHz machine. Everytime I click on the Network Pane it causes the system preferences to crash.
I've tried everything from rebuilding the permissions, to deleting certain pref files.
I thought I had fixed it the other day when I rebuilt the permissions, but the problem came back 24 hours later?
Has anybody else experienced this problems?
Thanks
T

arg..... tried everything you suggested and didn't work. The weird thing is I can sort of make it work. If I reboot and load system preferences before everything seems to finish loading it works if not it craps out, even after successfully booting it and then restarting it. Here's my activity log. I've pretty much have killed everything I recognize and with the exception of timbuktu that's about all I can see: MenuCal's I've already killed once and that did nothing so it's back in there.
