I got cause of this problem.
Inside the child window (Which I am closing using 'x' button causing the
exception)code I am using 5 events of that window.

 		1.WindowStateEvent 
           	2.ConfigureEvent 
            3.FocusInEvent
           	4.ResizeChecked 
 		5.DeleteEvent 

And in configure event I am using with [GLib.ConnectBefore] attribute for
calling that event ahead of all.

When I am commenting the focusin event and resizechecked event the code is
running fine.

Is there any problem in using both of this events? Or whether there is any
problem in using these two events in conjunction with the configure event
with Glib.ConnectBefore?

Please throw some light on this.

Many Thanks,

Libin

I have no idea what is really going on here, but it seems like an object is
disposed by your code before Gtk# tries to do that.

Set the environment variable "GTK_SHARP_DEBUG" to some value before you run
your program from the console. You should get a stack trace of the
GLib-Critical then. Post the stack trace to the list or file a bug report
with a small test case.
