I just looked at this and have found the error. I was not able to
reproduce your example, but in the process (for small files
which are not readable by the daemon - e.g. NFS mounted files
which root cannot read) I found the problem. Please test
out this beta version (next private message to you) 
and let me know if it works for you.

Please test cautiously,
