In a sense it's even worse, since expat is not a validating parser.  IMO
It shouldn't try to fetch the DTD unless it's explicitly activated by
the programmer.  There's not much a non-validting parser can do with the
DTD anyway.  In Thuban we worked around this by switching this off:

            parser.setFeature(xml.sax.handler.feature_validation,0)
            parser.setFeature(xml.sax.handler.feature_external_ges,0)
            parser.setFeature(xml.sax.handler.feature_external_pes,0)

Whether this works depends on whether the extra xml package is installed
and perhaps on the Python version.

IMO Skencil should not fetch SVG DTDs.  If the DTDs are necessary,
copies of the DTDs should be shipped with Skencil.

The code should be fixed so that no network connections are done.
