automatically downloading public keys no longer works.

[Dr. Sharukh K. R. Pavri.]

I am using mutt 1.4i w/ gnupg 1.0.7. Previously I could automatically
download the public key of the author of the mail if it was not already in
my public ring. I am unable to do this since upgrading to gnupg 1.0.7. I
have a basically stock install of both mutt as well as gnupg w/ no major
changes made to any conf/rc files. This is the output of gnupg now:

gpg: Can't check signature: public key not found

What am I doing wrong ? It used to work for mutt 1.4i w/ gnupg 1.0.6. At
present I use gnupg *only* w/ mutt.

Sharukh.
