I did change RenderStage so that it used a new osg::State::glDrawBuffers(..) + State::glReadBuffers(..) that does lazy state updating for these GL state variables to avoid calling GL when not necessary. If there is any third party code that calls glDrawBuffers/glReadBuffers but the OSG doesn't know about I guess this could introduce problems. During this dev work I did accidentally check-in a "cleaned up" implementation of osg::State::glDrawBuffers(..) that called itself rather than ::glDrawBuffers(), this caused a infinite loop. I fixed this yesterday so git master should be fine now. W.r..t setting Read/Draw buffers to GL_BACK, this should only be required for top level/viewer Camera's. I can look into the issue if you reproduce the problem with an existing OSG example let me know I'll try to reproduce the issue. It might also be worth you trying a clean check out of the OSG to see if that changes what happens.
