From d8b274bfd0efdc0763231701da7cc148a4f36d33 Mon Sep 17 00:00:00 2001 From: kmoore Date: Tue, 12 Jul 2011 14:40:16 +0000 Subject: [PATCH] Segfault on shutdown when confbridge is active When undergoing a shutdown and channels are kicked out of a bridge, a segfault occurs because ConfBridge tries to play sounds on the bridge after the underlying channels have been blown away due to the shutdown.
