Signing an email and sending it to a signature known recipient hangs Kmail-mobile.


Reproducible: Always

Steps to Reproduce:
Prerequisite: set up an OpenPGP signature for the user and the recipient

- Launch Kmail-mobile
- Click on 'Write New email'
- Enter a subject and a few words in the Composer text editor
- Open the 'Recipients' tab and enter the recipient's email
- Open the 'Actions' tab and click on 'Sign'
- Click on 'Send'

Actual Results:  
Kmail hangs indefinitely and two error messages appear in a yellow background.

Here is what I get in the terminal after I click on 'send':

Expected Results:  
The email should be properly sent and signed

I did manage to send from the n900 and receive the signed email once but when I opened it from another computer it was not signed at all.

Also, I was never asked to enter my password for the signature to be valid as it is the case in the desktop version.

atm the only way to stop kmail-mobile from hanging is to stop it from a terminal.
