yes, when using streams the directory information is lost and the files
referenced from the 'inline' nodes can not be found - of course it
should not result in a crash, I'll see if I can reproduce it now.
One way to use streams and make the loading of inlines work is to
manually set some paths on the PathHandler of the SceneFileHandler.
Normally calling SceneFileHandler::read() will add the directory where
the currently loading file is to the PathHandler, but when using streams
that directory is not known, so this step can not be done.

That is another way to work around this, of course.
Cheers,
Carsten
