Below selector work correctly on v1.7.2 but doesn't on v.1.8.0

$("form[name=frmMain] > table > tbody > tr:nth-child(5) > td > table:nth-child(5) > tbody > tr:nth-child(3) > td:not(td:first)")

I tested on Chrome 21.0.1180.75 m

This is log from console:

Uncaught Error: Syntax error, unrecognized expression: form[name=frmMain] > table > tbody > tr:nth-child(5) > td > table:nth-child(5) > tbody > tr:nth-child(3) > td:not(td jquery-1.8.0.min.js:2
