you can't pass GTK_LIST(mylist)->selection into remove_items and expect
things to work. obviously, upon removal of list items,
GTK_LIST(mylist)->selection has to be updated, this is done at the beginning
of gtk_list_remove_items() and then the list pointer you passed into the
function becomes invalid.

do this instead:

GList *copy = g_list_copy (GTK_LIST(mylist)->selection);

gtk_list_remove_items (GTK_LIST (mylist), copy);
g_list_free (copy);
