I realised that I was running a custom kernel, however the same Segfault occurs
when runing the the 'stock' ubuntu one.

output from working glxinfo

I'm not set up with the git sources, but managed to muddle-through with
building via the package system....
--
$ apt-get source libgl1-mesa-dri
$ sudo apt-get build-dep libgl1-mesa-dri
$ cd mesa-10.0~git1310311233.b16b3c~gd~s/
$ dpkg-buildpackage -b
--

After patching the file and installing the newly built package I was able to
run glxinfo without segfault. So that looks to be the problem solved.
--
$ sudo dpkg --install libgl1-mesa-dri_10.0~git1310311233.b16b3c~gd~s_i386.deb
libgl1-mesa-dri-dbg_10.0~git1310311233.b16b3c~gd~s_i386.deb

Thanks,
Simon.
