Ah. I wonder if I see the problem - the Windows binary installer for
bzr is built using py2exe, which only packs up modules that are
actually used by the code. So as core bzr doesn't use
xml.sax.saxutils, the bzrtools plugin doesn't work with it, as it
tries to import something which isn't included in the bzr package
(even though it is in core python).

But given that escape() isn't used anywhere in the dotgraph.py code,
why not remove the import in any case?
