The attached patch fixes a seg. fault in compare_csns() in syncrepl.c if it receives a sync cookie with an empty "csn=" value.
This has been fixed in HEAD.
syncprov_playlog() in syncprov.c generates such invalid cookies when replaying a sessionlog where no entries has been deleted. The patch also fixes this bug.
This should never happen, since the cookie is not generated if there were no deletes recorded.
