Read encrypted files

Hye,
Thx this wonderful add-on, I recently started to really use FireGPG (before I was using Thunderbird/Enigmail). And one thing is really annoying me : I can't have access/read attached files. I get something like the following text in the mail

"--------------080609040301060802070903
Content-Type: application/vnd.oasis.opendocument.text;
name"

But I don't see the file and can't even download it. Except this message everything is like there is no attachment. As I use GPG mostly to exchange files, it is really disturbing.

Is it a bug, is it a feature that is not provided, it is forecasted ?
