Ok, I've tried out  gpgme_ctx_set_engine_info function with the silly attached 

gpgme_ctx_set_engine_info return this error:

a.out: engine.c:308: _gpgme_set_engine_info: Assertion `file_name' failed.

Looking into engine.c i made this changes:

   if (!new_file_name)
     return gpg_error_from_errno (errno);

In this way the program list all keys stored into the specified directory but, 
in the end it segments. 
The problem comes from gpgme_release function.
With a little debug I found that  the signal SIGSEGV is raised into 
 free (info->file_name)
at the second iteration.
info->file_name seems correct, I wasn't able to discover the real problem.
