Comment (by pramsey):

 From the test, here is the crash sequence
 {{{
 -- Drop corrupted topology (with missing layer sequence)
 -- See http://trac.osgeo.org/postgis/ticket/5118
 SELECT NULL FROM topology.CreateTopology('t5118');
 CREATE TABLE t5118f (id int);
 SELECT NULL FROM topology.AddTopoGeometryColumn('t5118', 'public',
 't5118f', 'g', 'LINE');
 INSERT INTO t5118f(g) SELECT toTopoGeom('LINESTRING(0 0, 10 0)', 't5118',
 1);
