[Zope] Problem working around string.split issue

[Casey Duncan]

The problem is likely due to the fact that myFile.data
is not a string for large files, so you can't split
it. It is actually a PData object which segments the
data into chunks for better memory handling.

If you use the str() function on the file though, that
should give you what you want:

theData = str(myFile)
