Comment 3 for bug 736316

Step by step:
I opened the Contact Overview.
After waiting a few seconds, my Ubuntu One Contacts have been loaded. I can use them to write a Mail, view the details and so on, but if I try to change any field of a contact, the error Message is shown, if i press OK to save the changes. It doesn't matter, which field of the contact a change. Also if I add a character to the Name and deletes it, so that there is no change to be saved, the error message pops up when I press the OK Button.

PS: If you want a video, I could make it for you.
PPS: The Problem exists on both of my PC's. So it does not seem to be a problem with 32 or 64 Bit Ubuntu Version.
