Yes, it should.  In this case, imagine GNU libc 3 comes out, Debian
decides to migrate to it, and libraries linked against glibc 2 are
moved to /usr/i386-glibc2-linux/lib or what not.  Without the rpath
setting, ld.so will look for libraries in the new place, and
everything's fine.  With the rpath setting, though, it looks in
/usr/X11R6/lib instead, finds glibc3 libraries, and everything breaks
(you get lossage like trying to link in both glibc2 and glibc3, for

Yes, this has actually happened with the libc5->glibc2 transition; the
fix to "fvwm2 won't run at all" was "open up the binary with an editor
and put a zero byte where the rpath setting begins".  This sucked.  :-)
