	* gtk/gtktextlayout.c (gtk_text_layout_get_lines): remove some
	debug code that seems to have caused a breakpoint in valid cases

	* gtk/gtktextbtree.c (_gtk_text_btree_add_view): set the prev
	pointer on the first view when adding the second view, fixes
	crash when closing gtk-demo text test with active selection

	* gtk/gtktextbuffer.c
	(gtk_text_buffer_remove_selection_clipboard): don't leave dead
	clipboards in the list of clipboards - probably fixes #59836
