Shown used space does not match real used space

[Thomas Bechtold]

the ubuntu one gnome client show me that i use 42 MiB and the webpage (one.ubuntu.com) also show me that i use 42 MB. But in fact i only have the standard ubuntu one folder (shown in the gnome client)with 3 files (each about 8 kb). I have no music.
So why think ubuntu one i use 42 MB?
