Which content type is used by gmail for this attachment ?
If the checkbox is disabled then gmail either sends this with content disposition: attachment or they send it as application/octet-stream and that means that this is no bug because it's by design that you can't save a helper application.

I can't see a difference for handling application/octet-stream with 
http://mversen.de/mozilla/text/mozilla.rar between FF2 and FF3
