Just for information, I finally figured out the problem when trying to 
reproduce it, and I don't think it is a bug.

When a channel enters a Stasis application from the dialplan, the 
application is subscribed to this channel. But when the channel is hung 
up, Asterisk removes the channel from the application before emitting 
the ChannelDestroyed event, so the application is unsubscribed and does 
not receive this final event.

The behaviour is different for channels originated with ARI : in this 
case Asterisk will subscribe the application to the channel, so it 
receives all the events until the channel is destroyed.

I solved it by manually subscribing the application to the channel.
