PgAdmin crash on large data returned by a query

To "destroy" my Windows box I just have to execute in PgAdmin 1.16.1 the 
following query on any database:

select database_to_xml(true, true, 'http://myorg.org');

This will freeze my Windows 7 x64 box until I restart the computer.
Is there any chance to make PgAdmin a bit more "crash proof"?

Thanks,


Edson.
