Comment 2 for bug 513673

Andreas,
Sorry you are having problems with Ubuntu One. Looking at your log files I wondering if there is something you could try. There is a bug when setting the bandwidth preferences to the defaults (clicking on the checkboxes and not changing the values, leaving them at 0). Could you try deleting the ~/.config/ubuntuone/syncdaemon.conf file and restart the Ubuntu One client and don't set the bandwidth settings to the defaults.

Thank you for submitting this bug and helping to make Ubuntu better,
