 Replying to [comment:7 geoffp]:
 > I still have this, unfortunately.  I've attached a log + backtrace.  The
 segfault for me occurs at the first time I play a song with Rhythmbox
 after starting Jack + Pulse.

 I don't see any segfault in that backtrace. Segmentation fault means that
 a program crashes due to trying to access memory that it doesn't own. In
 that backtrace pulseaudio didn't crash - you stopped it yourself using
 ctrl-c.

 I assume you're running jackd in the realtime mode. How small buffers are
 you using in jackd? If they are very small, does increasing the jackd
 buffer size help? AFAIK the most likely reason for zombification is that
 the client (in this case pulseaudio) doesn't return from its processing
 callback fast enough. If you can't use pulseaudio with reasonably small
 buffers in jackd, then I guess this bug can be left open... It's another
 matter whether anyone knows how to fix this.
