Looks good as it ensures that there will always be a message there. It
seems to have been copied from somewhere though as the messages are wrong ;)

"expanding ratelimit string failed"
"failed to expand ACL ratelimit"


It would be interesting to know what causes the string to fail and
return NULL in this instance though. I haven't been able to trigger it
in my limited testing.
