Comment 4 for bug 1015228

Sorry, my last statement was wrong, this behaviour has occurred with Faenza pngs as well. It works for some icons, but not others. Faenza, elementary, humanity, tango, oxygen, and ubuntu-icon-theme all cause this, while the GNOME icons and a fresh icon I drew up do not exhibit this behaviour. This behaviour also only occurs in the ~/.icons or /usr/share/icons folder.

UPDATE: More playing around with a fresh icon I made brought some even more interesting results. When my icon was in a folder called 16, the icons changed to 16 (my icon was 16 pixels). When my icon was in a folder called 64 (same 16 pixel icon), the icons changed to size 64. If a folder is named after an irregular number, say 101, the icons seem to change to the closest regular number (128). The icons in the folder *do* need to be square for this to happen.

My hypothesis is that somebody attempted to implement a feature that would show icons in their native sizes (like nautilus does), but didn't implement the feature effectively (or intelligently in my opinion). By simply axing this feature (I am assuming my hypothesis is correct here), we can solve this bug.
