Interesting. From your last email it seems that the same happens even
with the normal (non-python) demo, right?

The only idea I have is that libmemphis parses the xml map data file
incorrectly because it opens the file in different encoding (I think
GTK normally uses locale encoding and not UTF-8, which might be the
problem). But it could be something else too.
