Same problem here with a dell d620 laptop and nvidia binary driver.
ooo fails to start, wine fails to start, 3d apps fail to start.
name of display: :0.0
glxinfo: xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.
Aborted (core dumped)
I'm more than happy to provide more information, but I can't seem to get a core. ulimit -u unlimited still doesn't produce a core file when running the above.
