That is equivalent to 'bash -c time', except that $0 is set to "ls"
instead of "bash" or "time" for the duration of the command (in other
words, the same crash as before, because you invoked time without arguments).

Much better - now you are actually giving time an argument.  Again, in
bash 3.0, you should not use time without a valid argument (at least, not
until I can roll a bash 3.0-15 that works around the coredump).  Or you
could upgrade to bash 3.1 (but remember to also use a current snapshot and
readline 5.1), where the problem has been fixed upstream.
