Problem with OpenGL on new X serverl

I have a crash when opening OpenGL. I have the same configuration than you :
ssh -X <host> ; XWin with glx extension activated.

Some of my investigations :

1. It's not caused by the X client OS (SunOS and Linux give the same crash)
2. It's not a problem with our application, glxinfo produce the same problem
3. It seems that the message "GetWindowProp - pWin or name was NULL"
is displayed before the crash, see my log in attachement.

I will download and check the XWin sources but I have not a lot of
time for debugging it so if someone have the same problem or want to
help me ...

Best regards,
