Version 98 changed the backend_qt4 toolbar so it is a true Qt toolbar, which
already has a layout. I guess you need to use the existing layout, rather than
adding a new one.
If that doesn't help you, please post a *short* standalone script that
reproduces the problem. Its hard to diagnose these things based on so little
information.
