Details:

I am attempting to use rdiff-backup to backup my Windows 7 workstation to my
linux server. The backup partially completes, then crashes in the middle when
it reaches the My Music folder in My Documents. Here is the error I receive.

Exception 'coercing to Unicode: need string or buffer, NoneType found' raised

Here is partial output of dir /a %USERPROFILE%\Documents
21/01/2010  04:41 PM    <JUNCTION>     My Music [C:\Users\Peter\Music]
21/01/2010  04:41 PM    <JUNCTION>     My Pictures [C:\Users\Peter\Pictures]
21/01/2010  04:41 PM    <JUNCTION>     My Videos [C:\Users\Peter\Videos]

Windows 7 and Windows Vista use Junctions in My Documents for My Music, My
Pictures and My Videos which symlink to the actual directories.

JUNCTION Explanation (NTFS directory symlink):

I tried excluding My Music, My Pictures and My Videos but that didn't work.
