[jQuery] IE 6 and jQuery 1.3.2 .load() issues

The following javascript works just fine when called from Firefox, but
IE 6.0.2900 chokes when it sees it:

$("#data_entry").load(myurl);

---- html ---
<div id="data_entry">
</div>

The exception I'm getting is:
Exception line 1642
Error: Exception thrown and not caught

I'm quite new to jQuery. I've been searching the bug list but haven't
seen this precise problem documented.
Can anyone with more experience reading the jquery codebase explain
what's happening where it's choking?

Thanks,
kmh
