mml-secure-epg-encrypt: GPG error: "Encrypt failed", "Exit"

mml-secure-epg-encrypt: GPG error: "Encrypt failed", "Exit"

[Peter Münster]

Hi,

With latest git-emacs, I get this error, when sending encrypted
messages:

mml-secure-epg-encrypt: GPG error: "Encrypt failed", "Exit"

The message is sent encrypted but the buffer stays in "*unsent mail*"
mode and the message is not copied to the Gcc.

Just after restarting emacs, there is no such problem, only later, after
some up-time.

What could be the reason please and how could I fix it?

TIA for any help,
--

Hello,

It seems, that the problem has been introduced by

Further information:

The problem is in `epg-encrypt-string'. Before commit
47b710a976d6e343d48b5170757a7971b0ac2966 `input-file' was nil, but after
the commit it is used because `sign' is true and the protocol is
OpenPGP.

But I don't know, why the use of a file matters here...
