can be ignored and closed i found my problem

trailing spaces at the end

That should be this issue:

Was the problem trying to upload files with traiing spaces then?

This error

is caused by the dropbox SDK failing to decode an error message properly so it would be useful if I can reprduce it.

I failed to reproduce it with file or directories with trailing spaces though...
