Hi Daniel, here's my example:
$ python
Python 2.7.11+ (default, Apr 17 2016, 14:00:29)
[GCC 5.3.1 20160413] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gi
>>> gi.require_version('Vips', '8.0')
>>> from gi.repository import Vips
>>> image = Vips.Image.new()
>>> gt = image.get_typeof("banana")
>>> gt
<GType invalid (0)>
vips_image_get_typeof() is the C function that's being called. It
looks up the GType of a bit of image metadata and returns 0 (invalid
type) if there's nothing of that name.

What would be the best way to test the return value of image.get_type()
for invalid?
