python-gdchart2: Can't use a list as data for setData method

Generating a PieChart works as advertised in the documentation, by
giving the data values to the setData method one by one:

myPie = gdchart.Pie3D()
myPie.setData(1, 2, 3, 4, 5)
myPie.setLabels(["One", "Two", "Three", "Four", "Five"])

But one can't build a list of data by other mean and then use it as

# assume both list have same length
mydatalist, mydatalabels = getDataFromSomeSource()
myPie = gdchart.Pie3D()

This results in this exception:
GDChartError: List of labels must have same length as data.

called like this, myPie._data contains:
([906.98000000000002, 2.5600000000000001, 92.459999999999994],)

setData method is defined like this:

364     def setData(self, *data):
365         """
366             Set pie data to be graphed.
367             mypie.setData(1, 2, 3, 4)
368         """
369         self._datalen = len(data)
370         self._data = data
371         self._conformanceCheck()

If defined like this:
364     def setData(self, data):

It will work correctly, but the call to setData will _always_ need to be
done as an array. So, documentation will need to be:

myPie.setData([1, 2, 3, 4, 5])

Which would be more consistent with the way setLabels works anyway.

Should I send the patch/bug report upstream to Debian?
