Comment 1 for bug 15485

I have a similar problem using kmail under Breezy:

To restate, when I receive a gpg encrypted email, kmail does not prompt for a
passphrase.
Instead the following is displayed:

Encrypted message (decryption not possible)
Reason: Crypto plug-in "openpgp" could not decrypt the data.
Error: Bad passphrase
  Encrypted data not shown.
  End of encrypted message

When I run eval 'gpg-agent --daemon' I get this:
can't connect to `/home/jim/.gnupg/log-socket': Connection refused
switching logging to stderr
gpg-agent[15200]: listening on socket `/tmp/gpg-I3IF9w/S.gpg-agent'
GPG_AGENT_INFO=/tmp/gpg-I3IF9w/S.gpg-agent:15201:1; export GPG_AGENT_INFO;

Workaround: save the msg.asc file to desktop. Open it with KGpg. Enter the
passphrase. The decrypted file is saved to the same directory (Desktop).
