libdbus-qt-1-1c2 0.60-6ubuntu8.1 (amd64 binary) in ubuntu dapper

 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 the Qt-based shared library for applications using the
 Qt interface to D-BUS.
 .
 See the dbus description for more information about D-BUS in general.
