That typelib error is coming from virt-manager's attempt to import
AppIndicator, which isn't used by all distros/desktop environments. It's
actually nonfatal in this case and just informative.

The actual error is:

Traceback (most recent call last):
  File "f:\Projects\virt-manager\virtManager\baseclass.py", line 46, in cb
    return func(*args, **kwargs)

I have never seen that error before, but I imagine it's something wrong with
libxml2 compilation or install. Do you have any other libxml using apps, and
if so do they work correctly?
