DBUS error on Debian Wheezy

[aguleo]

I downloaded Qt 5.0.0 for Linux 32-bit (411 MB) an installed it on Debian Wheezy.
I get the error, when building demo app:

Qt at-spi: error getting the accessibility dbus address:  "The name org.a11y.Bus was not provided by any .service files" 
Accessibility DBus not found. Falling back to session bus.
QXcbWindow: Unhandled client message: "_GTK_LOAD_ICONTHEMES"

Are there any missing packages?
