SEGV_MAPERR error gtk_widget_show_all?

[Brijesh <brijesh jadav einfochips com>]

Hi all

while running my application, i am getting SEGV_MAPERR signal. because 
of it, my application crash down. i have debugged using gdb and came to 
know that it is at the function call
	gtk_widget_show_all((GtkWidget *)curWidget).

where curWidget is a poitner to widget which has been hidden by 
gtk_widget_hide_all((GtkWidget *)curWidget) previously and curWidget is 
a pointer to GtkWidget which points to one dialog box in my application.


can someone help me out?

i have included entire stack trace.
