Why are you reallocating space for an image loaded from file ?
Shouldn't the texture dimension be a power of 2 ?

Where is attachment for COLOR_BUFFER0 ?
You should read the framebuffer object spec :
http://www.opengl.org/registry/specs/ARB/framebuffer_object.txt
Especially the part that begins by "If the GL is bound to the default
framebuffer"...
attachement to osg::Camera::COLOR_BUFFER1 is only valid for a newly create
framebuffer, not the default one.
