Hi Julien, It's me that submitted this change at http://www.mail-archive.com/osg-submissions@lists.openscenegraph.org/msg05568.html
It's hard to tell what's going wrong without the full code of your camera setup. In http://www.opengl.org/registry/specs/ARB/geometry_shader4.txt error 0x8da8 refers to FRAMEBUFFER_INCOMPLETE_LAYER_TARGETS_ARB and the document has possible cause for this error.
