Since the beta3, I'm no more able to sign or encrypt a message in kmail2 (even if nothing has changed between beta2 and beta3)


Reproducible: Always

Steps to Reproduce:
1. Setup your identity and crypto prefs with your own key
2. Try to write an email to yourself 
3. click sign & encrypt
4. Get error message
Actual Results:  
You have requested to sign this message, but no valid signing keys have been configured for this identity.

Expected Results:  
gpg selected and mail sended encrypted

Extract of .xsession-error ( kmail & co have been placed in debug mode )
