Comparing strace output for the two cases showed that when glxinfo was
run as "me" the opengl library was trying to load libraires from
/usr/X11R6/lib/dri/...

For reasons lost in the mists of time, my .bashrc file contained
this culpable line:

export LIBGL_DRIVERS_PATH=/usr/X11R6/lib/dri

Removing that did the trick...
