Summary0004677: crash when destroying cadet channel
DescriptionService crashes when trying to destroy a cadet channel.
It seems if this is always the case when a peer (A) has two open channels towards another peer (B), the other peer (B) closes one and A in turn closes the other one.
In this case GNUNET_CADET_channel_destroy () (at cadet_api.c:1594) seems to call GNUNET_MQ_send (mq=0x0, ev=0x1f19f60) at mq.c:369. Note the empty mq!

Program terminated with signal SIGABRT, Aborted.
