Xorg.1.0.log

I use X query on a remote server to launch an application. I can login remotely. This application works perfectly when used directly on the server, but makes X crash when used remotely. 
The client runs with xserver-xorg-video-intel 2:2.9.1-3ubuntu5, and the video chipset is Intel Corporation 82865G.
I run ubuntu lucid lynx.

Xorg.1.0.log attached.
