Environment:	Linux. Does not matter I think.	Attachments:	( 0) smfix.patch
Description:	ConfBridge uses bridge_softmix, which tries to create timer(in softmix_bridge_create function). Fails(ast_timer_open() return NULL value) so bridge initializes self-destruction(with ao2_ref(softmix_data, -1)) which tries to close non-existing timer in softmix_bridge_data_destroy function(softmix_data->timer is NULL and ast_timer_close tries dereference NULL pointer so crash)
