Re: Virtaal and Python warnings

[Simon Feltman <s feltman gmail com>]

Hi,

This seems to be fallout from the following change in glib:
https://bugzilla.gnome.org/show_bug.cgi?id=687659

The PyGObject ticket and commit you mentioned was to ensure PyGObject
works after the glib change. However, this fix was for PyGObject 3 or
"PyGI" which is the introspection version of the Python bindings. It
looks like Virtaal is using PyGTK and the older PyGObject 2 static
bindings. I see a back port of the fix for PyGObject 2 here:
https://bugzilla.gnome.org/show_bug.cgi?id=694108
https://git.gnome.org/browse/pygobject/commit/?h=pygobject-2-28&id=9456ba70fdb

But it is unclear if it is fully resolved based on the comments in the
ticket and it doesn't look like there has been a PyGObject 2 release
for a few years (the last tag is dated 2011-06-13 release 2.28.6).

Apart from testing and releasing a new PyGObject 2 from the
pygobject-2-28 branch. A different approach is to update the app to
PyGObject 3 and use the compatibility shim (pygtkcompat):
