Comment(by dnarvaez):

 Looks like it has to do with the WebKit2.WebContext, this simple example
 produces the same segfault:

 import os

 from gi.repository import WebKit2
 from gi.repository import Gio

 def _app_scheme_cb(request, user_data):
     path = os.path.join(activity.get_bundle_path(), request.get_path())
     request.finish(Gio.File.new_for_path(path).read(None),
                    -1, Gio.content_type_guess(path, None)[0])

 context = WebKit2.WebContext.get_default()
 context.register_uri_scheme("activity", _app_scheme_cb, None)
