The same error is returned with ZSyncer 0.4.6.

The error appears after clicking the sync tab in a given folder.
The objects we're comparing are DTML Methods, DTML Documents, Images, 
Folders, Page Templates, and Scripts.
In ZSyncer 0.4.6, the error is returned only when a folder on the 
source is not present on the destination.  The comparison and sync 
operations work fine when the folder's id and tree location is 
identical on the source and destination.  With ZSyncer 0.5.0-pre10, the 
"illegal data at start of file" error is returned if a folder on the 
source is not present on the destination.  If a folder's id and tree 
location is identical between the source and destination, the following 
error is returned (using ZSyncer 0.5.0-pre10)..

> Are both Zopes running on windows?

Yes.  Both are running Win2K Server.  I would love to switch to Linux 
or Mac OS X, but our sysadmins won't have it.
