Using a png with transparency works fine, but when the icon is losslessly compressed using optipng, transparency appears as black instead. This happens regardless of the compression level / arguments used.
I've attached 2 files, `debian-compressed.png` causes the black to appear instead of transparency, and was compressed using `optipng -o7 debian-compressed.png`
The other file, `debian.png` works fine, and isn't compressed.
