I'm having trouble writing a program using GPGME that is able to read the 
signatures of keys from a file. I've ensured that GPGME_KEYLIST_MODE_SIGS is 
specified and would appreciate additional eyeballs on it. I've tested it with 
the Debian keyring which has many signatures and not had any luck.

The code is at or can be cloned from

I'm using GPGME 1.14.0-1+b2 on Debian Bullseye (testing) with GnuPG 2.2.20 and 
libgcrypt 1.8.7.
