Using jQuery 1.6.2 and FF 5 on Win 7 Pro, if I have:

<div id="dialog"></div>
<div>
	<button>back</button>
	<button>next</button>
</div>

this selector finds no results:

$("#dialog ~ div button:contains('next')")

instead of the expected result of the button that contains the text 'next'.

If I provide the context argument:

$("button:contains('next')", "#dialog ~ div")

or a different filter on button:

$("#dialog ~ div button:last")

the expected button element is returned.

The expected result is returned in jQuery 1.3.2 on jsfiddle, but not in any later version available there.
