I'm confirming this bug. The replication steps are simple from a relatively fresh and updated Natty (64 bits) install.
1) Login to a new user account, or to the "Guest" session. 2) In a terminal, issue the "top" command 3) You should notice that desktopcouch-service is eating 100% of CPU. Workaround: It seems that login in the Ubuntu One service (from ubuntuone-control-panel-gtk) solves the 100% CPU problem. ** Changed in: desktopcouch (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/787583 Title: desktopcouch-service consumes 100% cpu -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
