Public bug reported:
I created a folder named "BrokenFolder" on a remote machine and filled it with
lots of empty files.
Reconnected the local machine to Ubuntu One and the client started to download
the files.
In the middle of a transfer I moved the folder containing the files being
downloaded first to another name ("SomeOtherFolder") and then moved it away
from Ubuntu One directory.
