Description
If I use the following selector:
$('~ span:first', this)
doesn't work - it won't found any element.
(this is input element, but it doesn't matter)
If I remove :first, than it works.
$('~ span', this) - THIS WORKS.
In old library 1.2.1.js the first example works:
$('~ span:first', this) - THIS WORKS IN PREVIOUS LIBRARY.

Why would his HTML be invalid? He doesn't want to find a child, he wants to find a sibling. ~ is the Next Siblings Selector.
In this case he wants to find all/first span sibling of every div.
I made a test case. If you switch between the various jQuery version you will notice that
jQuery 1.2.6 returned 1 for all tests
jQuery 1.3.2 returns 0 for Test 2 and Test 4
jQuery 1.4.3 fails to return 1 for all tests but Test 5.
This is a serious regression getting worse since jQuery 1.2.6
Your test case is using invalid HTML (for this particular problem) which is why your code is likely failing. If you wish to find a child element belong to a particular parent, you need to have that child actually be a child *of that parent* rather than outside of it. Not doing so would render your test case to not function correctly which is what is happening here.
