Warnings observed with Gtk2::Spell

["Ashwin Ramachandran" <rashwin28 gmail com>]

Hi All,
In my application, I am using GtkTextView and GtkSpell. However, I am facing issues, when they are used in the following way, in my 
application:

My application has a Left Screen[which has  a Gtk TreeView] and a
Right Screen, which has some widges. One of the widgets on the right screen is 
the TextView. As I move across different selections in the TreeView, different display
functions are called to display the widgets on the right screen.

There are a couple of display functions, which use the TextView and I have attached the 
Spell Checker to it.

for eg:
sub display_info1
{
  my $help_textview_1 = ...
  my $spell = Gtk2::Spell->new_attach($help_textview_1);
  my $help_text_buffer = $help_text_view_1->get_buffer();
  $help_text_buffer->signal_connect("changed", \&edit_changed);

 ..  .... Add other widgets here

}

sub display_info2
{
  my $help_textview_2 = ...
  my $spell = Gtk2::Spell->new_attach($help_textview_2);  
  my $help_text_buffer = $help_text_view_2->get_buffer();
   $help_text_buffer->signal_connect("changed", \&edit_changed);

  .... Add other widgets here
}

Whenever, I move across the tree selections, which calls different display functions in turn,
 I am observing the following error:
gtkspell-ERROR **: file gtkspell.c: line 626 (gtkspell_new_attach): assertion failed: (spell == NULL)
aborting...
Aborted

And after the above error, my application crashes.

Sometimes, I observe the below error as well:
GLib-GObject-CRITICAL **: g_object_set_data: assertion `G_IS_OBJECT

(object)' failed at /usr/share/osfr/tools/ddore.pl line 6278.

Segmentation fault

And my application crashes.

Am  I missing something here?

Any help in this regard will be appreciated. Many users of this application
are asking for spell checker.

Thanks
Ashwin
