 This is the message I get if I use a custom query with no results.
 {{{
 Quantum GIS was unable to determine the type and srid of column geom in
 (SELECT * FROM "public"."_ctr2k_av" AS "t_0") as "subQuery_0". The
 database communication log was:
 }}}

 I get no errors if I insert that layer from QGis GUI because if I not use
 a custom query the provider retrieve type and srid by the entry in
 geometry_columns.
