OpenPGP/Mime in KMail broken in Sarge

[Hendrik Sattler <ubq7@stud.uni-karlsruhe.de>]

Hi,

I only made the Sarge updates, lately:
ii  kmail          3.3.2-2        KDE Email client

But now KMail does not want to use gpg-agent any more. It just tells me, that 
gpg-agent is not running

The gpg-agent package is installed (and the computer was rebooted this 
morning). gpg-agent is running:
3291 ?        Ss     0:00 /usr/bin/gpg-agent --daemon --sh
$ echo $GPG_AGENT_INFO
/tmp/gpg-nDWDgZ/S.gpg-agent:3291:1

I even restarted it. My config is ok:
$ cat .gnupg/gpg-agent.conf
pinentry-program /usr/bin/pinentry
no-grab
default-cache-ttl 1800
$ readlink -f /usr/bin/pinentry
/usr/bin/pinentry-qt

Any suggestions?
