I'd rather not resolve it that way as, since that argument should never be 
NULL, checking for NULL will end up obscuring real problems elsewhere.

I've just tried simulating a speech driver start failure by trying to start one 
that doesn't exist. Doing this doesn't reproduce the problem. Could you please 
log with -ldebug,speech,spkdrv so I can try to figure out how it's failing?
