Comment 1 for bug 1523722

I am guessing this crash started to happen when we introduced the following change:
http://bazaar.launchpad.net/~phablet-team/telephony-service/trunk/revision/1144

It essentially pauses the stream and delete the old instance before creating a new one.
The backtrace shows an exception is raised in core::dbus::Bus::send_with_reply_and_block_for_at_most, and another thread shows a __pthread_cond_wait(), can it be some sort of deadlock on deletion?
