Here is a simplified addon:

import gi

xbmc.log('1', level=xbmc.LOGERROR)

gi.require_version('Soup', '2.4')
xbmc.log('2', level=xbmc.LOGERROR)

gi.require_version('GLib', '2.0')
xbmc.log('3', level=xbmc.LOGERROR)

gi.require_version('Grl',  '0.3')
xbmc.log('4', level=xbmc.LOGERROR)

from gi.repository import Soup
xbmc.log('5', level=xbmc.LOGERROR)

from gi.repository import GLib
xbmc.log('6', level=xbmc.LOGERROR)

from gi.repository import Grl
xbmc.log('7', level=xbmc.LOGERROR)

And the Kodi log which results from clicking on the addon,
exiting, and clicking on it again follows. Notice Kodi prints '1'--'7'
on the first run, but the second stops at '4'. Does gi rely on a full
exit to release its resources?
