1.5.2 autoupdate not working in folders with metadata

Autoupdate is not working in 1.5.2 if the shared folder has 'recover metadata' checked. 'Force update' is working.

What is 'recover metadata' ?

Can you give example of the files in the folder and post detailed log when you add a file to this folder?
