selector regressions in 1.3rc2

hi,
just tested the 1.3rc2, and it seems the attribute selector doesn't
work when selecting the anchor links:
$('a[href^=#]')
returns zero objects.
another very weird bug:
$('*').size()
shows zero results...
tested on FF 3.0.5 and Safari 3.2.1
I haven't filled a bug report yet, thought maybe you're already on it.
