Encrypt works fine, but decryption fails with

Warning: gnupg::decrypt(): decrypt failed in /home/idaho/test-gnupg.php on line 19

Downgrade gnupg to version 1.4.10 solves the problem. Seems that the problem is in gpgme_op_decrypt call - it returns value != GPG_ERR_NO_ERROR.


Reproduce code:
---------------
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
putenv('GNUPGHOME=/home/idaho/.gnupg');
$GnuPG = new gnupg();
$GnuPG->seterrormode(GNUPG_ERROR_WARNING);
$GnuPG->addencryptkey("lukasz@wasikowski.net");
$ciphertext = $GnuPG->encrypt("test message");
echo "Encrypted:\n" . $ciphertext;
$try= $GnuPG->adddecryptkey("lukasz@wasikowski.net",'test');
$decryptedtext = $GnuPG->decrypt($ciphertext);
echo "\nDecrypted:\n" . $decryptedtext;
?>


Expected result:
----------------
Encrypted:
-----BEGIN PGP MESSAGE-----
Version: GnuPG v1.4.10 (GNU/Linux)

[...]

-----END PGP MESSAGE-----

Decrypted:
test message

Actual result:
--------------
Encrypted:
-----BEGIN PGP MESSAGE-----
Version: GnuPG v2.0.16 (GNU/Linux)
