glxinfo crashed with SIGSEGV in __libc_start_main()

[Graham Inggs]

Binary package hint: nvidia-glx-180

After Intrepid to Jaunty upgrade, then activating hardware drivers, choosing OpenGL/GLX Information in nvidia-settings give "Fail to query the GLX server vendor".
I noticed a broken softlink at /usr/lib/nvidia/libGL.so.1.xlibmesa -> libGL.so.1.
There is no libGL.so.1 in /usr/lib/nvidia, but there is one in /usr/lib.
Running glxinfo gives a segmentation fault.
