Valid usage under GLES2 should use this feature so should never set COLOR_BUFFER0 and above. While the program shoudln't crash and I've now checked it the check against the new GL2Extensions::isDrawBuffersSupported() it very much looks like invalid Camera setup on the behalf of the user. This change is now part of snv/trunk and the OSG-3.2 branch. Robert.
