OK, so the shaft is broken just behind the panel... The danger with the superglue method is that it's very easy to spill glue so that the shaft gets stuck. However, if it's a clean break that "connects" well, and you're confident in your gluing skills, why not try. If not trying anything like that, you'd have to get the pot replaced for it to work anyway.
Of course, having done such an emergency repair, which might not last forever, I'd get the pot replaced at the first opportunity, e.g. the next time some service/maintenance work is due.
