Here's the backtrace using the current CVS version.
(I downloaded it just a few minutes ago).

#0  0x4207401d in _int_free () from /lib/i686/libc.so.6

FWIW, if I use the btaudio device for capturing audio from one of the
cards, and use the loopback cable to my regular soundcard for
capturing audio from the other card, I don't get the segfault.  It seems
that only when I try to use both of the btaudio devices that I get the segfault. 

Let me know what else I can do to help.
