I hate to barge into this thread, but it seems you chose to quit the
debugger right here rather than printing a backtrace. That might have
been significantly more useful so we can get an idea of the context of
this function call (i.e. how the program got there).
After pulseaudio gets a SIGSEGV, the first thing you should type into
gdb is `bt' (no quotes). Then you can quit.
