Problems with insert rule called from plpython

Hello,

I've noticed one problem by upgrading from postgresql-7.3.1 to 7.3.2.
The example of this problem looks like this:
  create table test (a int, b text);  create view testview as select * from test;
  create or replace rule testview_ins as  on insert to testview do instead  (  insert into test values (1, 'a');
insertinto test values (2, 'b');  );
 
  create or replace function testfun() returns text as  '  plpy.execute("""insert into testview values (3, ''c'')""")
return"test"  ' language plpython;
 

Now calling "select testfun()" shows this fatal error:
  FATAL:  SPI: improper call to spi_dest_setup  server closed the connection unexpectedly          This probably means
theserver terminated abnormally          before or while processing the request.  The connection to the server was
lost.Attempting reset: Succeeded.
 


This example worked in postgresql-7.3.1. In postgresql-7.3.2 works only
one command used in instead:
  create or replace rule testview_ins as  on insert to testview do instead  (  insert into test values (1, 'a');  );

Can you explain me this problem? Is it possible to reply also to my
email address, since I am not member of any postgresql mailing list.
Thanks.
