Texturing and pbuffer

I am using pbuffer (render to texture) to texturing a face with my rendering scene.
1- Rendering scene - in - 2- pbuffer - texturing - 3- face
Ok, nothing special for the moment,
just I can not texture object of my rendering scene anymore ?
Does someone have an idea ?
OpenGl limitation ?
openGl bug ?
personal limitation ?

I can only suggest you to try to visualize the pbuffer using DrawPixels before you use render to texture, so at least you know it's rendering.
