I have tried to use gpg-agent with version 0.5.13 and 14 and trying to create a backup fails with the following error:
===== Begin GnuPG log ===== gpg: cancelled by user gpg: encrypted with 2048-bit ELG-E key, ID XXXXXXXX, created 2005-10-05
"John Doe <address@hidden>" gpg: public key decryption failed: bad passphrase gpg: decryption failed: secret key not available ===== End GnuPG log =====
whereas the passphrase hase been correctly added to gpg-agent.
One odd thing is that the gpg key id (XXXX...) refers to the private part of the key I use for encryption/signing.
