Did you double check that you use the Qt version from Qt/2009.03/Qt/ for building your application? That is the default, but you may have changed it to another Qt version, e.g. the new 4.6-beta.
You do not need the *d4.dll files for the release version (they will not cause that problem, however). But you will probably need the QtSql4.dll (without 'd').
