Does it crash in the latest WebKit nightly build from <http://nightly.webkit.org/>?

[Rob Raguet-Schofield]

Yes, it crashes in "WebKit r44794 was built on 18 June 2009"

Attaching test case from duplicate bug

Since bug 30350 is a duplicate of this one, I'm attaching the same reduced test case, which should trigger this bug as well. Mouseover "fooooooooo" and continue to "baaaaaaaar" -> Crash.
