Comment 0 for bug 190688

This is a standard conformance issue (as of http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html)

The gnome-terminal is one of several applications that use an explicit suffix for their 'Icon' filed in their %.desktop
e.g.
Icon=gnome-terminal.png

instead of
Icon=gnome-terminal

Assuming I'm getting this right, this means that the application's icon will always use the PNG version and never the SVG (assuming it's available). As a subsequence, several visual effects, such as compiz scale, shift-switcher and more, will display an aliased icon.

Other applications with the same issue are:
gnome-dictionary
tsclient
eclipse
gparted
graveman
gconf-editor
cddb-slave
dotedit
gnome-ppp
hwdb
thunderbird
firefox

bum

gnome-compiz-preferences
ooo-template
synaptic
redhat-system-config-printer
vino-preferences
gucharmap
gnumeric
scim-setup
