UbuntuOne "add new folder" dialog frozen

[Alden Davidson]

Clicked on the UbuntuOne launcher in the Unity panel (dash?) on the left, and then clicked on the "add folder" button at the bottom of the UbuntuOne window.

It opened the file-selection dialog, and looked fine, but the cancel and open buttons didn't work (they don't even "light up" when a mouse moves over them), and I couldn't choose any files or open any different folders.

The close and maximize buttons in the top left of the dialog "light up" when a mouse moves over them, and I can press them, but the window doesn't close; it will maximize, but doesn't scale correctly - see included screenshot.

I could close the main UbuntuOne control panel, by right-clicking the launcher on the unity panel and clicking "quit", but the "add folder" dialog stayed open. I cannot re-open the main UbuntuOne control panel, since clicking on the launcher merely focuses on the "add folder" dialog.

Note: the info collected by apport says that my installation is "probably fresh install". This is not the case - my computer is upgraded fully (just ran sudo apt-get upgrade and sudo apt-get dist-upgrade about an hour before experiencing this issue). I usually do my upgrades through the terminal, so this *might* be why there isn't an upgrade log...?
