kmail doesn t sign/encrypt e-mails, broken pipe

Hi list,

I read "Using OpenPGP and PGP/MIME with KMail >= 1.7"[1] and installed a 
few libraries on my Gentoo System:

dev-libs/pth-1.4.0
dev-libs/libksba-0.9.8
dev-libs/libassuan-0.6.6
app-crypt/gnupg-1.9.10
app-crypt/gpgme-0.9.0-r1
dev-libs/libgcrypt-1.1.94

The installation is so great that I can do the 

> echo "test" | gpg -ase -r 0xDEADBEEF | gpg

'trick' and the 'eval "$(gpg-agent --daemon)"' is working fine. I can 
read decrypted mails but I can't encrypting mails in kmail and that is 
bad. When I try to send a decrypted mail I enter the pass phrase and 
everything seems okay but when kmail really sends the mail I got an 
error box with 

"Encyption failed: Brocken pipe"

What is the error here? What can I test so solve this problem? Any 
ideas? Is this a plugin error or an kmail error?

I read also the bug reports[2][3] in kmail but I unsure what is the 
problem here.
