DefaultテーブルのtoXMLは引数が３つなので、４つだとエラーになる。

	def toXML(self, writer, ttFont): 
		if hasattr(self, "ERROR"):
			writer.comment("An error occurred during the decompilation of this table")
			writer.newline()
			writer.comment(self.ERROR)
			writer.newline()
		writer.begintag("hexdata")
		writer.newline()
		writer.dumphex(self.compile(ttFont))
		writer.endtag("hexdata")
		writer.newline()

修正方法その１ progressを追加する。

site-packages/FontTools/fontTools/ttLib/tables/DefaultTable.py

def toXML(self, writer, ttFont, progress=None):
	if hasattr(self, "ERROR"):
		writer.comment("An error occurred during the decompilation of this table")
		writer.newline()
		writer.comment(self.ERROR)
		writer.newline()
	writer.begintag("hexdata")
	writer.newline()
	writer.dumphex(self.compile(ttFont))
	writer.endtag("hexdata")
	writer.newline()
