What steps will reproduce the problem?

When trying to add comments or rating on a page, I get a XML parsing error

What is the expected output? What do you see instead?

I see a popup with :

Erreur d'analyse XML : Emplacement : chrome://nepomuk/content/mgrComm.xul Numéro de ligne 8, Colonne 25 : onunload="onUnload()"> --------------------------------------^

What version of the product are you using? On what operating system?

I'm running Iceweasel 3.0.6 on Debian, with nepomuk-foxtrot-0.9

Please provide any additional information below.

The context in chrome/content/mgrComm.xul is :

<?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> <window script-type="application/x-python" id="mgrComm" title="Nepomuk comment manager for Firefox" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul&quot; onload="getPageURL()" onunload="onUnload()"> <!-- Use page to control the layout --> <page id="panelid"> <vbox> <separator />
