How to use (or debug) encryption?

Hello,

I just switched to 2.8.0 (current top of CVS) for routine use, and I
still notice some problms I've always had - whre I hoped updating
could fix these.  But eventually I'm just doing something wrong.

Question: how does one use signing/encryption - and how dooes one
debug this if it isn't working?

Assume I have a message ready for sending. In the "What now?" window I
select I select "More" => "Crypt..." and check "Encrypt".  Then I
click on "Send".  A window "Please select a GnuPG key to use or
signing" pops up, I select a key, and klick "OK".  A new window "Enter
GnuPG passphrase" pops up, I enter it, and click "OK".

Now I get an "Address or Header Error-1" window with an error message:
"couldn't open "/tmp/wd/0.pgp.32187.exmh": no such file or directory".

This is 100% repeatable - only the PID changes. ANd indeed there is no
such file - there is only a "/tmp/wd/0.msg.32187.exmh" file.
~/Mail/.exmhaudit does not show any interesting information either.

Am I doing something wrong?  And how can I debug this?

Best regards,

Wolfgang Denk
