syncdaemon ERROR with nfs mounted home

Using ubuntu-one on a client with NFS-mounted home directory, I receive an ERROR after touching a file locally in My Files. The file does not appear on the server, and an ERROR is captured in the syncdaemon logs as follows (and attached)

moose@office-desktop:~/Ubuntu One/My Files$ cat ~/.cache/ubuntuone/log/syncdaemon.log | grep ERROR

A quit and restart of the ubuntu-one client resolved this error. Attached are the logs just after resolution, and a screen shot showing the missing "nine.txt" from the web UI and ERROR immediately following file creation.
