As far as I understand it, no. With Fb 2 the ability to access the
new security database has been limited to accessing it via a view and
must be done using the Services API. However, trying to do it via
the standard API should not cause an AV but an exception.

Firebird 2.0.2 has not been released yet so I assume you are using a
snapshot build. The error you are encountering is occurring as a
result of a call from the client library. First double-check that
you are using the correct client library and, if not, try again with
the correct one. If the AV still occurs, please post a bug
description into firebird-devel as soon as possible, providing as
much info as possible (build numbers, server environment and model, etc., etc.)
