Indeed, and not limited to Ubuntu.

2 Mandriva systems: 2009.0, 2010.1

2009.0:

[stew at pavilion ~]$ /opt/lsb/bin/Xvfb -ac -x GLX :2.0 &
[1] 4925
[stew at pavilion ~]$ _XSERVTransSocketOpenCOTSServer: Unable to open socket for
inet6
_XSERVTransOpen: transport open failed for inet6/pavilion.e-artisan.org:2
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6

[stew at pavilion ~]$ export DISPLAY=:2.0
[stew at pavilion ~]$ glxinfo 
name of display: :2.0
display: :2  screen: 0
direct rendering: No (If you want to find out why, try setting
LIBGL_DEBUG=verbose)
server glx vendor string: SGI
server glx version string: 1.2
...

2010.1:

[stew at acer ~]$ /opt/lsb/bin/Xvfb -ac -x GLX :2.0 &
[1] 25676
[stew at acer ~]$ _XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/acer.e-artisan.org:2
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6

[stew at acer ~]$ export DISPLAY=:2.0
[stew at acer ~]$ glxinfo 
name of display: :2.0
Error: couldn't find RGB GLX visual or fbconfig

Simple test program confirms the original bug summary, that 
glXQueryServerString() returns NULL in the second case.

For kicks, I tried lsb-moblin, which is based on newer Xorg sources. For that
build, I get glx support returned in both cases. But it leaves us in the
situation described in bug 2734, where a bunch of xts5 tests fail.
