Comment 1 for bug 8343

Are there any particular file types that you've noticed this problem on? It
would help when checking out the problem (I assume this is with the Ubuntu icon
theme, right?)

I took a quick look through the code in the panel, and it looks like it should
scale down large images to the right size.

It looks like it isn't passing a size hint when loading the file, so SVG icons
will be rendered at their default size. If this size is smaller than the
desired size, then they won't be scaled up. Otherwise, it will be scaled down
(but this is slower than rendering at the desired size initially).
