Description Tom London 2008-01-20 13:26:30 EST
Description of problem:
pidgin-2.3.1-2.fc9 is segfaulting on me.

I ran with 'gdb' and got this trace:

*** PULSEAUDIO: Unable to connect: Connection refused
[Thread 0xb48fdb90 (LWP 8690) exited]
[Thread 0xb54ffb90 (LWP 8689) exited]

(pidgin:8241): GStreamer-CRITICAL **: 
Trying to dispose element play, but it is not in the NULL state.
You need to explicitly set elements to the NULL state before
dropping the final reference, to allow them to clean up.

Added a bunch of debuginfo packages (funny how some of them drag in real
packages as dependencies....).

Anyway, here is another gdb trace.  Seems easy to reproduce.... happens when
pidgin tries to generate a sound (at least sometimes).
