List Broken Data Source's Path

Hi everyone, I'm a very amateur Python user. I've managed to get the following, which I pieced together from here and there, working for the most part. I need to create a csv file which has a column showing the path to the data source which is broken. Everything works fine and dandy if I take out the dataSource part; when I add it in, it will run for a while and then fail. It seems to be getting tripped up on some mxd or data source it doesn't like perhaps? I have no clue. Here's my code:

import arcpy, os
path = r"H:\Plans\GIS Plans\2003"
f = open('BrokenMXD2003.csv', 'w')
f.write("Type, File Path, Layer, Broken Path" + "\n")
for root, dirs, files in os.walk(path):
    for fileName in files:
        basename, extension = os.path.splitext(fileName)
        if extension == ".mxd":
            fullPath = os.path.join(root, fileName)
            mxd = arcpy.mapping.MapDocument(fullPath)
            brknMXD = arcpy.mapping.ListBrokenDataSources(mxd)
            for brknItem in brknMXD:
                lyrList = arcpy.mapping.ListLayers(mxd)
                f.write("MXD, " + fullPath + ", " +
                if brknItem.supports("dataSource"):
                    f.write(", " + brknItem.dataSource + "\n")


print "Script Completed"

And here's the error I get:

Traceback (most recent call last):
  File "X:\Documents\Working Files\Broken Data Sources\", line 11, in <module>
    brknMXD = arcpy.mapping.ListBrokenDataSources(mxd)

    return fn(*args, **kw)

    return map(convertArcObjectToPythonObject, self.pageLayout.dataFrames)
AttributeError: 'NoneType' object has no attribute 'dataFrames'

It does run and create several lines of output, but this error appears when it gets near to the end of the mxd's in the directory. I haven't a clue what the problem could be, as I said I'm quite amateur. If anyone can see what it is, I'd be greatly appreciative. Thank you!
