Lists get improperly applied on empty documents

[barns]

List are producing even stranger behaviors now.

For instance, start from a blank page, click "insert bullet list" button, and start typing, you will get:

<p>dfdsfdsfsd</p>
<ul>
    <li>&nbsp;</li>
</ul>

Worse, you will not even be able to write on the bullet list any more.

Confirmed with Firefox. The selection is placed above the document when starting the list.

In IE instead, we have a different behavior. No list is created at all in the same TC.

I've fixed the FF behavior with [877]. No changes for the IE bug. I've opened #1291 for it.
