Selecting descendants of something:last yields duplicates

Description
I have a document with two <table> with class="toc", each containing a nested <ul> with a bunch of <li>s. $('.toc * li') will return all <li> elements as expected. $('.toc:last * li') returns all <li> elements in the last table, as expected, but returns each <li> four times. This means, among other things, that $('.toc:last * li').each(someFunction); calls someFunction() four times for every <li>. Example attached.

I have recreated your test case here Live Test Case, however using jQuery 1.4.3 this appears to be working fine now.

What do you mean by that? Your test case shows the exact behavior Catrope reported. Using Opera 10.62 I get 12 alerts when opening your test saying "One/Two/Three-B" 4 times. Instead of only getting 3 alerts (one for each li).
Another test case. For every jQuery version > 1.2.6 the result of $('.toc * li').length is different from $('.toc:last * li').length although there is only one .toc element in my test case and thus the results should be the same.
$('.toc * li').length correctly returns the same as $('.toc li').length (3 for my test)
But $('.toc:last * li').length returns the #non-li-descendants of .toc X #of li-descendants of toc (12 instead of 3).,
This seems to happen no matter what PSEUDO selector your use in the selector
