gnupg and CVS exmh

Ok, with the glimpse trouble sorted out, I've turned my attention to
GnuPG. With the previous version of EXMH, I was able to send signed
messages. With the new version, when I try to choose a key using the
option in the Crypt menu, no keys are listed, and if I tell it to sign
the message and hit Send, I see an error like:
couldn't open "/tmp/john/0.pgp.90673.exmh": no such file or directory.

I tried looking through the scripts to see what might be up, but I'm
not familiar with TCL and didn't make much progress. Have I simply
forgotten to set an option in the Preferences?

Thanks


John
