I've working on my problem, and the data allocation seem solved. (Or maybe it never appeared and I misjudge the debug info)
Now it's the gpg engine which throws a no data error. I've got this gpgme debug output, can someone ather information from it (I myself don't understand it quite well). For information, before this op_verify call, my program is making calls for keys and web of trust management without problems.
