Recently I started having trouble saving my .gpg files.

At first I figured "bah probably some transient bug in Emacs trunk", but
after trying it out with emacs23, I see the problem is not in
Emacs trunk.
The error I get is (see the appended backtrace):

Opening output file: Encrypt failed: ((exit) (invalid-recipient (reason . 0) (requested-recipient . "36DB083C608CC24C")))

It turns out the problem was simply that my encryption key was expired.
Could someone figure out how to get a more helpful error message?
