I replaced that icon file (the wrong one) with on of the other svg's and that fixed it (after a gnome-shell restart).
Notes:
* The left panel in Activities, the one with the shortcuts, apparently caches the icons, reason why I had to restart gnome-shell. The application finder tab did refresh the icon.
* Also, this is why launchpad report says I have a modified file in the package.
