[Thu Jul 21 13:44:54.093373 2016] [:error] [pid 6431:tid 2843577200] [client ] PHP Fatal error: Call to undefined method Crypt_GPG_SubKey::usage() in /opt/webmail/plugins/enigma/lib/enigma_driver_gnupg.php on line 437, referer: https://xxxxxxxxxxxxxx/?_task=settings&_action=plugin.enigmakeys
I got the exact same error a few days ago. It appears that roundcube resets the php's "default include_path" variable, so installing Crypt_GPG via Pear in the php/lib dir doesn't help. Manually downlading the library in the enigma/lib dir solved for me. I also dropped a note about this and enigma's configuration here http://notes.sagredo.eu/node/35#enigma
