And so are a lot of dialogues, e.g. of network manager applet, IIRC. GNOME 2 had a really nice and consistent default look and I had never the wish to change it. GNOME 3 is hard to read for my old eyes (too dark) and I could not change the look to sth. readable and consistent. But I'm sure, Debian Jessie will have a nice GNOME 3 (at the ago of 17 or 18 by then) for me, again :~)
