The following seg fault has started occurring since I rebooted my PC a few days ago (whereas it's normally on for weeks at a time). This is probably triggered by my sound system (Alsa, Jack, ...?) not being initialised properly, but it seems to work OK in other applications. Unfortunately I can't help much more for a couple of weeks, so apologies if this isn't enough information to spot the cause of the problem.
