gpg --list-sigs takes forever on my box.  Here's a one-liner (FSVO
"one" :) that has slightly different output format, but runs in just a
few seconds on my box:

  gpg --fast-list-mode --with-colons --list-sigs |egrep '(^pub|5DF19E2B67A7B584)'| perl -ne 'if($_ !~ /^pub/ and $last_line =~ /^pub/) { print $last_line;} $last_line = $_;' | cut -d: -f5 | xargs gpg --list-keys |grep '^pub'

It uses --fast-list-mode, which speeds things up considerably because
it leaves out a lot of the information, particularly the names.  I get
the names back by running gpg --list-keys on the output.

It also uses --with-colons, which prints out the data in a format
that's easier and more reliable to parse.  --with-colons prints out
the long form of the key id, which is the last 16 hex digits of the
fingerprint instead of the last 8 as are more commonly used.  That's
my key id in there for test purposes; you'd need to plug your own in,
or have that be a parameter in a shell script or bash function or
whatever.

David -- if you're following this, any chance of something like this
being a built-in option in a future version of gpg?
