duo gamer doesn't work after game app crash,system bluetooth settings crash.

What steps will reproduce the problem?
1.dungeon hunter 4 app crashed while playing with duo gamer(the game doesn't 
support duo gamer natively by gameloft,so i use btstack & blutrol
2.open the system bluetooth setting in order to reconnect duo gamer,but setting 
interface crashed
3.then it's a little complicate,i found some game app(such as wild blood)which 
support duo gamer natively doesn't work with it any more.
uninstalled btstack & blutrol,still not work.
so i aptitude purge them in the terminal and manually delete some preference 
file,and reboot.
wild blood works.
reinstall btstack,wild blood still works.
reinstall blutrol,system bluetooth setting crashed(comfirmed that file 
permission is correct),turn on and off bluetooth repeatly between btstack and 
bluetooth setting,there is a chance that avoid crash and connect duo gamer,but 
wild blood or dh4 still doesn't work.
i've attached both hci_dump.pklg and btstack log here and notice that there are 
some strange event
"DAEMON_EVENT_CONNECTION_CLOSED 0x12b3200
BTSTACK_EVENT_DISCOVERABLE_ENABLED 0"
in the rear end of the long log file.
consider that i've played with btstack for several weeks and the crash things 
just happen today,is there any relation?is there any system file 
corrupted(because btstack and blutroll did work for a long time,just bugged 
today even after packages purged and reinstalled) or just a bug?
i will do more tests on another i-device but the network here is not very 
well,i need some time to download big game apps.
What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
newest version of btstack and blutrol,ios6.1 on ipad

Please attach a package log, as described here:

The Duo Gamer mode of Blutrol uses the official ExternalAccessories API from 
within the games. BTstack isn't involved with that. (I know, Blutrol is a mixed 
bag of stuff).

In general, don't use BTstack prefs to switch between the stacks, only use it 
to disable BTstack if there's a need for it.

Try deleting Duo Gamer in iOS Bluetooth and rebooting.
