quick question: is there a call to PassiveWindow::init() somewhere? Is
the OpenGL context that is to be used by the PassiveWindow active at
that point?

^^^^
this should probably be done before osgInit, but it also is the default
with OpenSG 2.0 - I don't think this is related to your problem though.
