Hi Robert,
I tried but failed to reproduce the problem in the osg examples. It
must be some subtle difference in the way I set up my scene in my app.
I changed my viewer to the QOSGWidget implementation instead of using
the GraphicsWindowEmbedded in a QGLWidget and that fixed the crash.
Sorry I couldn't reproduce it, but at least there is a work around if
others run into this issue.
Cheers,
Morne
