[External Deps] update dbus-glib to 0.75

[Frederic Peters <fpeters 0d be>]

Hello,

NetworkManager now[1] requires dbus-glib 0.75 but GNOME blessed
external dependency is 0.74.

[1] http://svn.gnome.org/viewvc/NetworkManager?view=revision&revision=3752

Could the release team give its approval for the version little bump ?


Thanks,

        Frederic
