Pidgin should use themable icons for systray
Wheezy’s Pidgin takes its systray icons explicitly from the hicolor icon theme (instead of the current theme) rather than from current theme.
icon_path = g_build_filename(DATADIR, "icons", "hicolor", icon_sizes[i].dir, "apps", icon_sizes[i].filename, NULL)
