Hi every body, please let me add another way to reproduce the error :

../../src/xcb_io.c:183: process_responses: Assertion `!(req && current_request && !(((long) (req->sequence) - (long) (current_request)) <= 0))' failed.

I post here because the #419501 seems to refer to another line than the 183 one

1] Create a simple open GL application that makes its rendering in your own created X11 window.
-> Create your opengl context and X11 window in the main application thread.
-> do not use automatic extension loops ... (use glxXXXXXX functions)

2] instead of running your rendering loop from the main thread, run it from another thread ...
-> it crash if you run the loop in a second thread,

I'm running

-> ubuntu 10.04 LTS - the Lucid Lynx - released in April 2010
-> inside a Virtual Box (running under windows XP 32)

hoping it will help
