Ok.
for me It doesn't work if you have two ebo on same vbo
with only one primitiveset all works fine
tested with core context and compatability context

here is code how I create textured quad
Code:
Geometry* geom = new Geometry;
Vec3Array* coords = new Vec3Array(4);
(*coords)[0] = corner+heightVec;
(*coords)[1] = corner;
(*coords)[2] = corner+widthVec;
(*coords)[3] = corner+widthVec+heightVec;
geom->setVertexArray(coords);
Vec2Array* tcoords = new Vec2Array(4);
(*tcoords)[0].set(l,t);
(*tcoords)[1].set(l,b);
(*tcoords)[2].set(r,b);
(*tcoords)[3].set(r,t);
geom->setTexCoordArray(0,tcoords);
osg::Vec4Array* colours = new osg::Vec4Array(4);
(*colours)[0].set(1.0f,1.0f,1.0,1.0f);
(*colours)[1].set(1.0f,1.0f,1.0,1.0f);
(*colours)[2].set(1.0f,1.0f,1.0,1.0f);
(*colours)[3].set(1.0f,1.0f,1.0,1.0f);
geom->setColorArray(colours,osg::Array::BIND_PER_VERTEX);
osg::Vec3Array* normals = new osg::Vec3Array(4);
(*normals)[0] = widthVec^heightVec;
(*normals)[0].normalize();
geom->setNormalArray(normals, osg::Array::BIND_PER_VERTEX);
DrawElementsUByte* elems = new DrawElementsUByte(PrimitiveSet::TRIANGLES);
elems->push_back(0);
elems->push_back(1);
elems->push_back(2);
elems->push_back(2);
elems->push_back(3);
elems->push_back(0);
geom->addPrimitiveSet(elems);
DrawElementsUByte* elems2 = new DrawElementsUByte(PrimitiveSet::TRIANGLES);
elems2->push_back(0);
elems2->push_back(1);
elems2->push_back(2);
elems2->push_back(2);
elems2->push_back(3);
elems2->push_back(0);
geom->addPrimitiveSet(elems2);
