A html activity does segfault when it closes. I added gdb to the process and got the following traceback:

Program received signal SIGSEGV, Segmentation fault.

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())

-1, Gio.content_type_guess(path, None)[0])

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