Summary:                    mutex 'current_dest_chan' freed more times than
we've locked! on bridge() from dialplan
Description: 
Sometime when bridging I get this error:
[Apr 29 15:36:00] ERROR[5486]: lock.c:407 __ast_pthread_mutex_unlock:
features.c line 5872 (bridge_exec): mutex 'current_dest_chan' freed more
times than we've locked!
[Apr 29 15:36:00] ERROR[5486]: lock.c:438 __ast_pthread_mutex_unlock:
features.c line 5872 (bridge_exec): Error releasing mutex: Operation not
permitted

normaly bridging goes okay or it tells me the channel does not exist

this line is features.c is generating the error:

ast_channel_lock(current_dest_chan);
