I confirm the Python scopes are now, after having applied the pygobject
update, working on a Xenial 64-bit system and still working (= no
regression) on a 32-bit one. Thanks!

Please don't apologize for doing great work :-) I haven't really worked
on pygobject for two years now. Thanks for fixing this!

Thanks for the investigation. I uploaded the new pygobject to fix this.

[Jean Christophe André]

After having installed 2 identical VM (PXE + preseed), with the only
difference being the architecture (32-bit vs 64-bit), I can now confirm
that the Python scopes are working on a 32-bit install and crashing on a
64-bit install, with exactly the same requests made on both sides
(calc:1+1, man:calc).

[Jean Christophe André]

Not sure if this helps but it appears this problem only occurs on a
64-bit system. I did a Xenial 32-bit installation recently and the
Python scopes (I tested calc: and manpages:) worked properly. On a
Xenial 64-bit installation, even with the very last updates (especially
the recent libunity-core), it still crashes.

[James Henstridge]

One last comment: I tried downloading upstream pygobject 3.20.0 (which
was released two days ago), and the scopes run fine using the Xenial
typelib.

So I think the underlying problem is that we've got a problem of version
skew, with the versions of gobject-introspection and pygobject currently
in Xenial being incompatible.  We either need to downgrade gobject-
introspection (and rebuild typelibs for any affected packages), or
upgrade pygobject.
