Comment 16 for bug 1179903

I got exactly the same behavior on my personal (i386) and professional (amd64) computers, both running Ubuntu 13.04 and connected on the same Ubuntu One account.

If it can help, here is what I get when I start oneconf-service in debug mode (the log shown here is from Ubuntu 13.04 i386):
$ /usr/share/oneconf/oneconf-service --debug
