Java script error when trying to add a content to advanced profile

I thought that is Advanced Profile, not Panels bug...

Ok then, please advise, what thing can cause problems with javascript here ?

Thank you.

I have also noticed there is a strange link....

mysite.com/javascript%3A+void%28%29

And the bit of java code in page source may help:

  <script type="text/javascript" src="/misc/jquery.js"></script>
<script type="text/javascript" src="/misc/drupal.js"></script>
<script type="text/javascript" src="/modules/jquery_update/compat.js"></script>
<script type="text/javascript" src="/modules/vote_up_down/ajax_vote_up_down.js"></script>
<script type="text/javascript" src="/modules/panels/js/panels.js"></script>
<script type="text/javascript" src="/misc/collapse.js"></script>
<script type="text/javascript" src="/misc/autocomplete.js"></script>
<script type="text/javascript" src="/modules/panels/js/lib/dimensions.js"></script>
<script type="text/javascript" src="/modules/panels/js/lib/mc.js"></script>
<script type="text/javascript" src="/modules/panels/js/lib/form.js"></script>
<script type="text/javascript" src="/modules/panels/js/display_editor.js"></script>
<script type="text/javascript" src="/modules/panels/js/checkboxes.js"></script>
<script type="text/javascript" src="/modules/panels/js/modal_forms.js"></script>
<script type="text/javascript">Drupal.extend({ settings: { "panelsAjaxURL": "http://mysite.com/panels/ajax" } });</script>

Also another screenshot attached

Please, help
Thank you

EDIT:

I have updated jquery and now I have error: An error occurred while attempting to process the pane configuration modal form..

Ok, I used the solution to saving the panel before editing and it's working fine so far. Acording to: http://drupal.org/node/238139#comment-935354
