Can we get a newer version of Webkit here? According to the
AIR 1.0 user agent string, you're on Webkit v. 420+. That
corresponds roughly to Safari 2.X.
Moving to Webkit v. 523+, corresponding roughly to Safari
3.0.4, would help a lot here. A *lot* of Webkit bugs and
limitations (i.e. scriptable XSLT processing, etc.) were fixed in
the Safari 3.Xs / v523 Webkits.
