YAZ & Perl bindings (ZOOM)

Hi everybody,

I'm programming a tool to collect some records from the Z3950 server of the
BNF (Bibliothèque Nationale de France). When I try to query this database
with yaz-client, everything is good, as you can see in the yaz-client
trace[1].

But when I try to get the same result via the Perl bindings, I don't have
any result. The script is available as a gist on GitHub[2].

What did I miss? Is there a way to see the query sent by the ZOOM module?

Thanks in advance.
