One other issue that may help locate this problem. Other than gnupg-agent, what does enigmail use for passphrase caching? Is it possible that something in that is screwed up?
In "System / Prefs / Encryption / PGP Passphrases" I see two lines:
Remember PGP Passphrases (bold)
A supported PGP passphrase agent is not running.
