Thank you Sebastian.

Is there a fix to this solution. In other words is this an issue? Can this version be used in production sites?

This sounds like a permissions error.  Can you confirm that the application pool identity and the site identity have permissions to that folder?  This is not a general problem with the release (this site is also running it).
