libdbus-glib-1-2-dbg 0.74-4 (i386 binary) in ubuntu intrepid

 D-Bus is a message bus, used for sending messages between applications.
 Conceptually, it fits somewhere in between raw sockets and CORBA in
 terms of complexity.
 .
 This package provides support for debugging programs that use the GLib-based
 shared library.

 See the dbus description for more information about D-Bus in general.
