GPG Error on Kmail

[Hakan Hekim]

Hi,
I am using Kmail as mail client. Two weeks ago I generated 2048 bit DSA and ElGamal key pair and begun to sign and encrypt my mails with Kmail.
But when I want to sign a mail now, Kmail is giving this error message;

This is error message of GnuPG;
gpg: skipped '0x3DF5FE9E': secret key not available
gpg: [stdin]: clearsign failed: secret key not available

I can sign documents from command prompth.
What can be the problem.
Thank you
