Testing with Chrome 27.0.1436.2 canary on MacOS 10.8, I do not see a crash. So I could see the test animating, I changed the given testcase to:

-----------
<style>
@-webkit-keyframes move {
  0% {
    width: -webkit-calc(50% - 100px);
  }
  100% {
    width: -webkit-calc(50% - 200px);
  }
}

#something {
  -webkit-animation: move 2s;
  background-color: blue;
}

</style>
<div id="something">hello</div>
------------
And I observed it animating as expected.

In summary:

Chrome 27.0.1436.2 canary MacOS 10.8: GOOD
Safari Version 6.0.2 (8536.26.17) MacOS 10.8: CRASH
WebKit Nightly r140374 MacOS 10.8: GOOD (tested as I had it lying around)
WebKit Nightly r145355 MacOS 10.8: GOOD

Simon - can you confirm the versions of WebKIt that you are seeing this crash on? Looks very much like this is already fixed..

It does seem to be fixed. I'll find out what rev fixed it later.

Fix range is http://trac.webkit.org/log/trunk/?rev=116917&stop_rev=116914

I suspect http://trac.webkit.org/changeset/116914 fixed this.
