Fix for GtkTextView::find crash

[Hans Breuer <hans breuer org>]

testtext crashes on me if I use Edit/Find.

The crash occurs from the idle function first_validate_callback()
when calling gtk_text_view_update_layout_width ().

The exact cause appears to be, that 

widget = GTK_WIDGET (text_view) 

fails, because the text_view is already deallocated/destroyed.
(instance->g_class pointing to garbage)

By removing the idle functions in gtk_text_view_destroy ()
it works.

Ok to apply ?
