I have the exact same issue. I am running SOGo 1.3.14 on debian squeeze with Dovecot for IMAP and when I right click on a folder and click 'Sharing...' all I get is a small box that says:
Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /SOGo/so/jacks/Mail/0/folderINBOX/acls. Reason: Error reading from remote server >From reading the mailing lists it looks like I need to configure folder sharing in Dovecot, but is that all I need to do to get rid of this error, or is there something that I need to add to my Apache config?
