[Zope] Part-time tracebacks

I seem to have fixed it btw but in a different way.

All I did was to cast the object to a string and this seems to have fixed
the problem:

	data=str(self.the_docs.xml.data)

This should work for all the files that I'm interested in, so until it
breaks I'll leave it that way.

|>pdb> type(obj)
