gda_init needs to be the first libgda call in your application, so you
should move the gda_config_save_data_source right after gda_init.

Apart from that, have you tried adding a HOST or HOSTADDR parameter to
the connection string? That is, make it be

if you connect to the "error" signal on the GdaClient, you'll get a
description of the error. This should help you in finding out what the
problem is.

in libgda/testing you've got code that works. Which is what you're
doing, so it seems it's not a code problem, but a problem with the way
you're accessing the database (connection string, I'd say).
