Kwallet does not work

[MERLIN Philippe <phil-deb1.merlin@laposte.net>]

Hi,
On Debian Sid AMD64
Since last update Kwallet is out, i don't know why and how i can correct this 
problem.
Kontact start very slowly more 2 minutes normally it is immediate,  he does 
not ask for the password of the wallet so i must give manually the password to 
every account of reception.
If i try Configuration of Kontact it's indicate for password Wallet is 
deactivated in the configuration system.
What can i do, google does not help me.
Kwalletmanager5 does not work nothing appears on the screen.
