Status changed to 'Confirmed' because the bug affects multiple users.

Same for me. Runnig Xubuntu 12.10 Quantal.

According to this discussion thay are facing the same problem in debian sid and FreeBSD 9. You might understand more of it then I do. And they are providing a workaround that worked for me.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=634930

***** WORKAROUND ******

I have found that the problem is the expired X.509 certificates.

Here is my easy workaround to solve this bug.

1. Remove the file where the X.509 certificates are stored.

rm usr/share/gnupg2/com-certs.pem

2. Remove your gnupg configuration folder.

rm home/benutzer/.gnupg/

That's all. Should work for every version. Enjoy.

I hope it helps.
