Issues using pgsql2shp with a postgis table with null geometries

[gabrimonfa]

The table has 7120 rows, 50 have null geometries and some of them are at the beginning of the table. Server is PostgreSQL 9.5 with postgis version "2.2 USE_GEOS=1 USE_PROJ=1 USE_STATS=1".

Desired behaviour

The shape is created with all the rows, null geometries in the table are null geometries in the shapefile.
Or it would be possible to add a null handling policy as in shp2pgsql.

Actual behaviour

pgsql2shp 2.4.4 (ubuntu 18.10 package)
The exported shapefile has 7070 rows (as the number of rows with not null geometry in original table), but apparently they are the first 7070 rows, some rows with not null geometry are missing.
All is working correctly if I use a "where geom is not null" clause.

pgsql2shp 2.5.0 (package from apt.postgresql.org in ubuntu 18.04)
Segmentation fault

Could you attach a link to data file, or some SQL to synthetically generate a table that demonstrates the behaviour?

Table creation:

CREATE TABLE public.ticket_4209 (
    id integer NOT NULL,
    geom public.geometry(Polygon)
);

COPY public.ticket_4209 (id, geom) FROM stdin;
1       \N
2       \N
3       0103000000010000000500000000000000000000000000000000000000000000000000F03F0000000000000000000000000000F03F000000000000F03F0000000000000000000000000000F03F00000000000000000000000000000000
\.

Command invocation:

pgsql2shp -f /tmp/test.shp -h host -u user -P password -g geom dbhame "SELECT * FROM public.ticket_4209"
