Collision wonky after changing static properties

[GoogleCodeExporter]

What steps will reproduce the problem?
Create a non-static body. Run a few steps of the simulation. Set it to
static (0 density). Other objects won't collide with it anymore.

What is the expected output? What do you see instead?
Objects should collide; they don't. At least not properly.. they sort of
slow down but pass through like jelly.

What version of the product are you using? On what operating system?
2.1.0; Linux version 2.6.28-15-generic running on amd6

Please provide any additional information below.

Sample code:

void Object::setDensity(qreal dens) {
    Q_ASSERT(m_body != NULL);
    if(dens != density()) {
        for(b2Fixture *f = m_body->GetFixtureList(); f; f = f->GetNext()) {
            f->SetDensity(dens);
        }
        m_body->SetMassFromShapes();
        emit propertyChanged();
    }
}

Fixed. I now automatically set the body's velocity to zero when you make it 
static.

See the updated Bridge example.
