ubuntuone-syncdaemon crashed with TypeError in open_control_panel(): constructor returned NULL

[Julie]

Hi!

Since Ubuntu 13.10 (maybe before that also), Ubuntu One is not working correctly. I get notifications that One is syncing documents etc, but when I try to open Ubuntu One, it shuts down immediately. When I login to the Ubuntu One website, I only find old files, so the files I thought were synced are actually not.

Anyone having the same problem? What can be done to fix this?
