The actual fault was ast_pickup_call where the target chan was unlocked too early - see bug18654.diff2.txt
Moved app_directed:pickup_do() to features:ast_do_pickup().
Now functions below all now use the new ast_do_pickup()
app_directed_pickup.c:
pickup_by_channel()
pickup_by_exten()
pickup_by_mark()
pickup_by_part()
features.c:
ast_pickup_call() </pre>
