SOLVED: Avant-Window-Navigator Stacks Applets not working under Python 3

So, all of a sudden my AWN Stacks applet stop working... right after the switch to Python 3 (blame on you Arch Linux!!!).

BUT!

... I traced the issue back to its origin so there is a way (as of today quite a dirty one) to solve it:

$ gedit /usr/share/avant-window-navigator/applets/stacks/stacks_applet.py

(You may need to sudo it)

Find line 271, comment it and change it to:
pixbuf = IconFactory().scale_to_bounded(pixbuf, 1 * size)
(or to pixbuf = IconFactory().scale_to_bounded(pixbuf, size) if you're not a Captain Obvious fan)

Save and exit.

Restart AWN.

Done.
