Still present in Lucid Lynx alpha 3 with the "Ambiance" and "Radiance" themes.
But, interestingly, it goes away when you use the following themes:
Homosapien
Kin
Clearlooks
Turrican
Apart from Clearlooks, these are all from the "community-themes" package.
It's obviously theme dependent. I've attached a screenshot of my Lucid desktop running Homosapien, and you can see that the Banshee and Pidgin icons are displayed correctly. (I've moved the window controls back to where they should be, this is actually Lucid.)
