When the user hovers over the top element and then moves the cursor down onto
the element which appears, WebKit will crash.

I have simplified the following code to the bare minimum required for the crash
to occur.

<style type="text/css" media="screen">
.nav li {
        display: inline;
}
.nav .primary_nav li ul {
        width: 160px;
        display: none;
}
.nav .primary_nav li:hover ul {
        display: block;
}
</style>
<div class="nav">       
        <ul class="primary_nav">
                <li class="drop">
                        <!-- The crash has something to do with the width of
this element. -->
                        <!-- When the mouse moves off of the right edge of this
element, it crashes. -->
                        <a href="#">1234567890</a>
                        <ul>
                                <!-- The length of this element makes a
difference too. -->
                                <!-- The mouse must move from one element
straight into the other. -->
                                <li><a href="#">987654321</a></li>
                        </ul>
                </li>
        </ul>
</div>
