filename too long problem

[Eric S. Johansson]

running rsnapshot for backing up Windows PCs, I'm getting an error message that 
looks like:

rsync: readlink "/Administrator/My Documents/MIT 
OpenCourseware/DiscreteTimeSignalProcessing/6-341Fall-2005/6-341Fall-2005/NR/rdonlyres/Electrical-Engineering-and-Computer-Science/6-341Fall-2005/244BA331-167F-463A-A10C-FCD390D067A8/0/midexam_soln.pdf" 
(in das) failed: File name too long (91)

I'm using Delta copy on the Windows PC and rsync 2.6.9 on ubuntu 7.10.  I 
suspect I'm getting bit by this bug.

If I am, are there any workarounds?
