I'm not sure what extra the OSG can provide. You can enable GL error testing per attribute by setting the env var OSG_GL_ERROR_CHECKING to ON, and this will give you a bit more feedback on which StateAttribute produced the error, but save from checking errors after every OpenGL call there really isn't too much more it can do without seriously impacting maintainability and performance. Perhaps better education on issues of using OpenGL/OSG and tracking down errors like this is required. This isn't just an OSG issue though, knowing OpenGL is a real asset.
