I seem to have an issue where I will be using emacs for a while, and eventually something happens which will corrupt all org buffers, and make them unviewable (the buffer refuses to display, but otherwise does not affect the rest of my emacs session).  The error I get is "line-move-partial: Invalid face".  I can switch to text-mode and see it normally.
<div><br class="webkit-block-placeholder"></div><div>I&#39;m using emacs version <a href="http://23.0.0.1">23.0.0.1</a>. &nbsp;I&#39;m using org-mode version &nbsp;5.13a. &nbsp;This seemed to coincide to my upgrade from org-mode version 4 to 
5.13a. &nbsp;This happens on both terminal and x-windows versions of emacs.</div><div><br class="webkit-block-placeholder"></div><div>Has anyone experienced this issue before? &nbsp;Any ideas on how to solve it?</div>
