I traced git-svn and discovered that the error is due to a known problem in the SVN APIs. ra_serf does not drive the delta editor in a depth-first manner as required by the API [1]. Instead, the calls come in this order:

 1. open_root
 2. open_directory
 3. add_file
 4. apply_textdelta
 5. add_file
 6. apply_textdelta

This is a known issue [2] and one that the Subversion folks have elected not to fix [3].
