Ubuntu One does not update reliably/predictably

Binary package hint: ubuntuone-client

Ubuntu One is reporting that all my files are up-to-date. But the contents of my local replica are different from the contents of the online replica (which I can verify).

package: ubuntuone-client 1.0.3-0ubuntu1
release: Ubuntu 9.10

What I expected to happen: when I add/modify a file in the local ubuntu-one folder, that it would update to the cloud.
What happened instead: I have newer files locally that have not updated to the cloud; ubuntuone-client reports, however, that all files are up to date.
