I presume FD 4 is pointing to the file named in ${tmpmenu}.  You should
probably close FD 4 before attempting to read from the file, to be sure
all buffers are flushed.

Another way to build up a command for later execution would be to use
an array instead of a file:

  zcmd=(zenity --list --window-icon="${run_path}icon.png" ...)
  for (( some loop )); do
    zcmd+=($a "some thing" "etc.")
  done
  "${zcmd[@]}"
