Strange error when compiling matplotlib with PyQt4 via pyinstaller - matplotlib

Question

My headaches of trying to compile PyQt4 and Matplotlib are seeming pretty endless.
Here is my test program test.py
from PyQt4 import QtGui, QtCore
import math
import sys
from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt4agg import NavigationToolbar2QTAgg as NavigationToolbar
import matplotlib.pyplot as plt
and here is my attempt to freeze this file by the command line
pyinstaller -w --onefile test.py
(tested with no options - pyinstaller test.py - with identical results)
And here is my console output:
16 INFO: wrote C:\Users\Tyson\Desktop\PHS3031 Lab1.2 - Alpha\test.spec

I'm attempting to do this on Windows 7 with Python 2.7.
It appears there's some empty string which was expected to be a filename, but this error obviously exists outside my code.
Any and all help appreciarted.
Thanks,
Tyson

It looks like the PyInstaller is having a problem with the cache which it uses to not read all the sourcefiles every time.
In the %Appdata% folder is a pyinstaller folder which store the cache in the bincache* folder. Maybe it helps to clean the cache and try again to run the pyinstaller
