Webkit Sample when Safari frozen

This is an issue I have been having for some time with Safari, and still have
using the latest nightlies.
It happens on any website, and makes Safari crash eratically. Here are the
steps I followed:

1) Navigate to any website.
2) Scroll down the page before it has finished loading completely.
3) Page freezes and beachball appears, force quit necessary.

- Loading the same page again might work, as crashes occur randomly.
- If I don't attempt to scroll until page is finished loading, page will load
just fine - scrolling doesn't cause any freeze afterwards.
- It seems that the disk is being accessed just right before beachball
appears/freeze occurs.

I have attached a sample of the process when it is frozen. This is an issue
that occurs on a regular basis on any website, requiring to force quit Safari
many times a day. I believe the issue appeared with the first betas of Safari
4.
