Indeed, with non-free Nvidia driver, I haven't more issue. Because libgl
is diverted by nvidia driver.

But, if you don't use non-free nvidia driver (nouveau, ATI, Intel...) ;
libgl will use DRI module 64 bits inside of 32 bits.

Indeed, to fix this into ia32-libs, we have to fix it into :
package : libgl1-mesa-glx_7.5-3_i386.deb
So ; ./mesa_7.5.orig.tar.gz

if (arch is x86-64) {
  if (built in 64 bits)
    path = /usr/lib/dri
  else if (built in 32 bits)
    path = /usr/lib32/dri
}
else if (arch is i386) 
  path = /usr/lib32/dri
