Version:            (using KDE KDE 3.4.0)
Installed from:    Unlisted Binary Package

I'm using the packages from http://pkg-kde.alioth.debian.org/kde-3.4.0/

My Key is on a OpenPGP smartcard (http://www.g10code.de/p-card.html)

If I try to encrypt/sign a mail using this key, KMail hangs and never returns. In the background I see this process:

gpg --no-sk-comment --status-fd 41 --no-tty --charset utf8
--enable-progress-filter --command-fd 43 --sign --detach --armor -u 0F2B3C20E772CFE9

I'm never presented the questions about the card's PIN. Encrypting using gpg on command line works.

So I guess you are not prepared to get something other than a question for a passphrase from gpg?

For reference, the output of gpg:
~~~~~~~~~~~~
huehnts@blackbox:~$ gpg -u 0F2B3C20E772CFE9 --detach-sign kurz/kmail-gpg
gpg: detected reader `Omnikey CardMan 2020 00 00'
gpg: signatures created so far: 1
gpg: DBG: asking for PIN 'PIN [sigs done: 1]'

PIN [sigs done: 1]
Enter PIN:  
~~~~~~~~~~~~

Please present the question for the PIN to the user; this might also affect other KDE apps like Kopete and stuff. I'll try that later.
