As reported on the Windows' thread (here), I too have been experience a sync error throughout yesterday and today. I presume it is as a result of the same bug referenced by Bradley. I have attached my logs for your information.
6761.Archive.zip
Also, unrelated to this, I note that there is a strangely named file in the Logs folder, 'awesomium'. I have not noticed this before. I presume there is nothing dodgy about this file.
