[Zope] ZODB conflict error AFTER adding an 'Access Rules'

Hi all, I've added an 'access rule' to my zope/CMF/plone site. Since then, I'm getting several errors in the console output like this: 2003-09-10T12:28:00 INFO(0) ZODB conflict error at /myroot/museum/share/js /share.js (6 conflicts since startup at 2003-09-10T12:16:58) ------ 2003-09-10T12:28:01 PROBLEM(100) Localizer The thread number 1656 don't has a re quest object associated. My access rule sets an attribute into the session object and changes skin (CMF 1.4 feature) . Any idea? If I remove the access rule, the errors disappear. Regards, -- Jean
