By running demo.py from the topleveldir of the source tree (instead of
from inside examples/):

LD_LIBRARY_PATH=/usr/local/libosinfo/lib/ GI_TYPELIB_PATH=/usr/local/libosinfo/lib/girepository-1.0/ python examples/demo.py
/usr/lib/python2.7/dist-packages/gi/types.py:43: Warning: GError set over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
The overwriting error message was: Incorrect root element
  return info.invoke(*args, **kwargs)
Traceback (most recent call last):
  File "examples/demo.py", line 6, in <module>
    loader.process_path("./")
  File "/usr/lib/python2.7/dist-packages/gi/types.py", line 43, in function
    return info.invoke(*args, **kwargs)
gi._glib.GError: at line 18: Namespace prefix xi on include is not defined
