Looks like segfault has been addressed. However the slave complains "Can't use projected tetrahedra without scalars!". The problem is that the slave is rendering before all the properties for representation have been set. The volume mapper doesn't have the "ArrayName" set. That gets set soon enough and the rendering happens just fine.

The issue arises when the slave's view is "linked" with that of the server.

The faulty render occurs because of some Qt widget are getting filled. Unfortunately we already left the Notification method from the session, so we can not use that information from the session to disable those render calls.

pqDisplayRepresentationWidget::onCurrentTextChanged(...)

A solution might be to have a static field on pqView that allow to disable any render to happen while we are processing remote request across several calls.

Seems to be fix, but the wrong tag segfault seems to occurs sometime...
