I'm using Ubuntu 10.10, fully updated. I have tried to sync my ~/Documents and ~/Pictures folders; U1 replicates the directory structure, but no files are uploaded.

Next I tried to sync a single file inside ~/Ubuntu One and it was synced. Then I tried to put a directory inside ~/Ubuntu One and, again, the directory structure was replicated, but no files were synced. All the files have the "syncing" icon, however.

The latest syncdaemon.log is below:
