DBusGProxy issues

It would be glad if someone can help me regarding the following issue. I
use dbus-glib bindings so that I can publish a Gobject on the bus.
I've two processes(A and B) communcating over the session bus. Process A
is a daemon kind of application to satify different needs. Process B is
a kind of application which comes in and goes out on a need basis.
Generally, process A makes remote method calls on process B using
DBusGProxy. Both the processes publish its own glib gobjects on the bus.
I've an issue with the following use case.
1. Process A makes a remote method call on Process B using Proxy, with
some time out of 45 sec.
2. In some cases, Process B dies or exits before it could respond with a
method return. (This can't be eliminated, this is as per design).
So, what happens is that Process A waits for the timeout of 45 secs and
then returns a error message. But, the expectation is that Process A
should come out the call immediately, as Process B died. 
What can be wrong here?
I use dbus_g_bus_get to get a connection to a session bus, and create a
DBusGProxy to publish glib gobjects on the bus. And more thing is that I
never clean up the connection acquired by dbus_g_bus_get, as it is a
shared connection. I tried cleaning up the Proxy instance on the Process
B end, but it caused Process A to exit(which should never be the case
for me.)
