This backtrace seems to be polluted by some C++ stuff?

This happened in older version of pavucontrol when no device could be identified by PulseAudio. Has been fixed months ago.

[jstedfast]

well, it's in 0.9.10 which is the latest release afaict

[jstedfast]

oh, the c++ stuff I think is just the Google SIGSEGV handler that is used by gnome apps

[lennart]

Interesting that you run pavucontrol 0.9.10. And I was pretty sure the last version I released was pavucontrol 0.9.6!

Here's the patch:

http://git.0pointer.de/?p=pavucontrol.git;a=commit;h=c80c710d05ef5f29cf2394d32edc18f61eda4018

It's part of 0.9.6 which has been released 3 months ago. You run 0.9.5.
