&gt; When trying to run org-refile on an org entry, I&#39;m getting the<br>
&gt; following error:<br>
&gt;<br>
&gt; while: Invalid regexp: &quot;Invalid content of \\{\\}&quot;<br>
<br>
</div>Can you give us your Org version, your Emacs version and a recipe<br>
to reproduce this problem?  Refiling works fine here.<br>
<br>
Thanks,<br>
