I'm testing the glslDevil debugger with a simple (and working) SFML application in Linux + NVidia. But it always fails in the window creation step:

W! Program Start
|  glXGetConfig(0x86a50b0, 0x86acef8, 4, 0xbf8228c4)
|  glXGetConfig(0x86a50b0, 0x86acef8, 5, 0xbf8228c8)
|  glXGetConfig(0x86a50b0, 0x86acef8, 8, 0xbf8228cc)
|  glXGetConfig(0x86a50b0, 0x86acef8, 9, 0xbf8228d0)
|  glXGetConfig(0x86a50b0, 0x86acef8, 10, 0xbf8228d4)
|  glXGetConfig(0x86a50b0, 0x86acef8, 11, 0xbf8228d8)
|  glXGetConfig(0x86a50b0, 0x86acef8, 12, 0xbf8228dc)
|  glXGetConfig(0x86a50b0, 0x86acef8, 13, 0xbf8228e0)
|  glXGetConfig(0x86a50b0, 0x86acef8, 100000, 0xbf8228e4)
|  glXGetConfig(0x86a50b0, 0x86acef8, 100001, 0xbf8228e8)
|  glXCreateContext(0x86a50b0, 0x86acef8, (nil), 1)
E! Child process exited
W! Program termination forced!

And the code that fails:

#include <SFML/Graphics.hpp>
#define GL_GLEXT_PROTOTYPES 1
#define GL3_PROTOTYPES 1
#include <GL/gl.h>
#include <GL/glu.h>
#include <GL/glext.h>

int main(){
    sf::RenderWindow window{ sf::VideoMode(800, 600), "Test SFML+GL" };
    bool running = true;
    while( running ){
        sf::Event event;
        while( window.pollEvent(event) ){
            if( event.type == sf::Event::Closed ){
                running = false;
            }else if(event.type == sf::Event::Resized){
                glViewport(0, 0, event.size.width, event.size.height);
            }
        }
        window.display();
    }
    return 0;
}

Is It posible to solve this problem? or get around the problem to continue the gslsDevil use?.
