problem with gtk view

["Rajesh kumar" <rajesh_drdo rediffmail com>]

hi

I have created textview widget through GLADE application and showing
char strings on text view which is created by glade interface designer 2.0
available with Fedorra-1

The problem is that sometimes it is working correctly but
other times segfault is coming. There are two threads are running One for main
thread transmitting and other continuously looking for message

As I think it is a problem with showing window with
textviwew widget bcoz with other window problem is not there

 

The part of code with problem:

 

      ReceiveWindow=create_rcv_FreetextWindow
();

      GtkTextBuffer
*buffer;

      printf(\"\\n
window created\\n\"); //sleep(5);//every time  when it fails  it is failing after showing printf 
statement

      gdk_threads_enter();//for
making thread safe

      //sleep(5);

      printf(\"\\n
thread entered\\n\");

      gtk_widget_show(ReceiveWindow);

      printf(\"\\n window
showed\\n\");

      gdk_threads_leave();//for
making thread safe

      printf(\"\\n
theread leave\\n\");

      for (i=0;
i<100;i++) printf(\"\\a\");//for sound alert on receing the message

      printf(\"\\n
window showed\\n\");

 

      buffer =
gtk_text_view_get_buffer(GTK_TEXT_VIEW
(lookup_widget(GTK_WIDGET(ReceiveWindow),\"textview1\")));

 

      
gtk_label_set_text(GTK_LABEL(lookup_widget(ReceiveWindow,\"Fromnamelabel\")),\"\");


      printf(\"\\nText
Message is %s\\n\",x_fields->val);

 

      This is errors
coming before giving segfault in run time

            (fot:19108): Gtk-CRITICAL **: file
gtktexttag.c: line 1932 (gtk_text_attributes_ref): assertion `values != NULL\'
failed

 

            (fot:19108): Gtk-CRITICAL **: file
gtktexttag.c: line 1932 (gtk_text_attributes_ref): assertion `values != NULL\'
