GL_MAX_TEXTURE_SIZE returning 0

Dear all,
A collegue is trying to run an OpenSceneGraph application through Chromium.
However, any application with a textured scene segfaults.
After some investigations, I found that OSG relies on GL_MAX_TEXTURE_SIZE
to resize a TEXTURE_2D to the nearest power of 2.
Under a Chromium cave configuration, GL_MAX_TEXTURE_SIZE returns 0,
therefore OSG tries to allocate a texture of (0,0) size which causes the
segfault.
Could anyone confirm that bug ?
Regards,
Vincent

The piece of code to insert within osgviewer render loop :
GLint _maxTextureSize;
glGetIntegerv(GL_MAX_TEXTURE_SIZE,&_maxTextureSize);
printf("GL_MAX_TEXTURE_SIZE : %d\n",_maxTextureSize);
My configuration :
3 linux PC under Fedora 5
GPUs : ATI Radeon X800 GTO with fglrx drivers / the situation is similar with NVIDIA GPUs.
OSG version : 1.2
Chromium version : 1.9.
