One new piece of evidence.  Running 'gpg --list-keys' returns many lines
like

$ gpg --list-keys
gpg: checking the trustdb
gpg: [don't know]: invalid packet (ctb=00)
gpg: keydb_search failed: invalid packet

then correctly lists a few.  It looks as though the database is
corrupt.  Now if I knew what it is called, or where it lives, I could
restore a backup copy.  Does anyone know?  Thanks
