Error on document preview in Share (Alfresco Community 4.0)

[fmerighi]

Hi. I've installed  Alfresco Community 4.0 on tomcat 6, and all the additional components (openoffice, imageMagik, etc.).
I've experienced the same or a similar bug as described in https://issues.alfresco.com/jira/browse/ETHREEOH-2282.
In particular, when i try to access to a document preview in share, an error message appears, something like "Unable to load document preview from server".
The server log says:

This is the error occurs for all the type of documents?
I mean doc,txt,pdf.
Or for particular type of documents only?

[fmerighi]

I tried with pdf, word and also txt documents created within share itself, the behaviour is the same.
But if i try to have a preview of documents shared in sample project Web Site Design Project, it works.
It seems to be a permission issue, but the documents have standard permission scheme, and i access to them using a manager user.
