Here's another little script[1] that might help you, Pal -- it looks
at all binaries in $PATH for any missing shared libraries (it would
have caught your firefox problem, for example). Some of them are false
positives as some packages (not many) include optional binaries that
require extra libs (for instance, colord package -> colord-sane binary
can report as "bad" if you don't have package sane installed because
you don't have a scanner :) ). It may help you find more broken things
directly instead of by chance.

#!/bin/bash
#
# Search all binaries in $PATH for missing shared libs

IFS=:
for BINDIR in ${PATH}; do
  BINS=$(find "${BINDIR}" -type f -printf "%p:")
  for BIN in ${BINS}; do
    ldd "${BIN}" 2>/dev/null | grep -i "not found" | cut -d ' ' -f1 | \
      xargs -I '{}' printf "${BIN},%s\n" '{}'
  done
done

It prints out a CSV-type file, just change that final printf format to
your liking.
