When you say "the audio mixer", do you mean the applet titled "Audio Volume" or something else? Perhaps a 3rd-party applet?

Unfortunately the backtrace appears to be generic and useless. Without being able to reproduce this locally, I don't think there's much chance of fixing it. :/

Yes - that one.

I was not able to reproduce the issue - I use the audio applet a lot and didn't get this again.

All right, thanks. If it happens again, let's re-open and try to investigate further.
