I turned SCRIPT_DEBUG on and it made it a little easier, but not much,
to figure out what is wrong.  The jQuery libraries are packed so all
of the code appears on one line.  I can noarrow it down to the Sizzle
CSS Selector Engine:

Message: Invalid argument.
Line: 19
Char: 35190
Code: 0
URI: http://localhost/wp-includes/js/jquery/jquery.js?ver=1.3.2

LIne 19 contains 39657 characters - all of the code is on one line and
obviously too much to post here in wp-hackers.  You can see the code
by looking at jquery.js in your WordPress install, my development
version on my laptop is at:

My problem seems to be in draggable or droppable.  I disabled some of
my JS that preloads a theme setting to see if I could help isolate the
problem and the page loads correctly.  As soon as I drop an element
the Debugger kicks in this code begining at chatacter 35190.  At that
character the following code is flagged


There is no obvious mapping from the code above to the actual SizzleJS
source code to gain any insight from:


I am guessing I have some sort of a JS selector problem but am not
sure how to track it down.
