Just to confirm, are we talking about the same test, the one with:

 X-JAM-MSGID: 2:221/360.0 5e16299e

If so, it works here.  I'll email you pictures of what I see.

I have Enigmail configured for Automatical Decrypt/Verify.

BTW.. When I am viewing that message in a fresh session, there is a bit
of a delay (maybe 5 seconds) before the passphrase pops up.  Maybe
you're not waiting long enough, or another window is sitting on top of it?
