I battled the same thing in dmedia for quite a while, and I think the issue was having a mix of Gtk2 and Gtk3 installed, needing to explicitly require the correct versions before importing from gi.repository. Here's an example:

import gi
gi.require_version('Gtk', '2.0')
gi.require_version('WebKit', '1.0')
from gi.repository import Gtk, WebKit

I attached the dummy-client script I use in dmedia to automatically run JavaScript unit tests in embedded webkit, so you have a full working example (or at least it's working for me right now).

Sadly, that doesn't seem to work for me; Jason's dummy-client gives the same error:

$ python dummy-client.py
Traceback (most recent call last):
  File "dummy-client.py", line 54, in <module>
    scroll.add(view)
  File "/usr/lib/python2.7/dist-packages/gi/types.py", line 44, in function
    return info.invoke(*args)
TypeError: argument 1: Must be Gtk.Widget, not WebView

I've been trying to reproduce this, haven't been able to. My hunch is something different in the packages we have installed might be the problem.

But obviously this affects dmedia too... if Stuart is having this problem, others probably are too, or will in the future.

Stuart, can you try this on a fresh install in a VM or something? I can too, although I'm off for a bike ride right now.

I tested this on current oneiric, and it works fine. So I'm closing this for oneiric. Do you need this working on natty for an SRU? If it's important, we can presumably find an SRU to fix it.
