To be 100% clear: Uri has sent me the attached message msg-dump-bad.txt,
which I extracted to file.txt and file.txt.asc.
If I call gpg (1.4.7) with: "gpg --verify file.txt.asc file.txt"
I get: "gpg: can't handle this ambiguous signature data"
That's all the information I have. As far as I can tell, the message
itself looks perfectly fine.
