Comment 3 for bug 868887

I have no idea. I removed Ubuntu One from all of my machines as it was too unreliable, especially deciding randomly to stop syncing files and not give any indication that had happened. It also tried to create as many .u1conflict files as possible even though I only ever changed files on one machine. This issue is what convinced me to give up on Ubuntu One completely. I tried Dropbox instead and have never had a single issue.
