I would like to use the clone tool with texture paint, but as soon as I choose Texture Paint, the mesh is white, and I cannot paint on it.
I created a new UV Map, after I project the image from view, the image of reference appears well on the mesh in Object Mode, but I get this white color in Texture Paint Mode. I followed this tutorial : https://youtu.be/p4ngVoGIj1Q?t=15m56s but the version of Blender is not the same, so the settings are a bit different.
I tried to play with the clone settings, the options in the shader menu : GLSL/Multitexture, but nothing changes.
Would you know how to use this clone effect in Blender 2.72b ?

This is when I paint :
This is when I click on the uv map : it is not the same result as the previous painting :
