Fixes: Crash in Server->IC connection due to wrong upchaining
Fixes: Crash in Server->IC connection due to wrong upchaining

RevBy: Michael Hasselmann
Details: dispose handler was chaining up to finalize handler
of parent class instead of the dispose handler,
and the finalize handler was never chaining up.

On some newer platforms (Arch Linux, Ubuntu 11.10) this would cause
a crash when the application disconnected from the server,
with warning messages like:
process 6813: arguments to dbus_connection_unregister_object_path() were incorrect, assertion "path != NULL" failed in file dbus-connection.c line 5727.
