gpgme error no data for op_verify

[Josselin Jacquard]

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.

Thx in advance.
