I guess the combinaion of multilib (which IMO is a bad idea in general) plus usrmerge is confusing dpkg-shlibdeps, but I don't think this is in principle a bug in dpkg-shlibdeps. Check your /etc/ld.so.conf.d/* for anything included libx32, and check if «dpkg-query --search» knows about that pathname, and if it's the canonical one or a symlinked one. Thanks, Guillem
