This is a tool that displays Debian bug reports in mutt. You can then directly read all messages sent to the bug and reply. The messages are fetched directly from the web interface, so there is no delay between requesting bug and getting it per email.
This tool was originally written by Christoph Berg, I've made some modifications to make it work in arbitrary directories.

gpg --verify is quite slow when you have large keyrings included (like the
debian keyring). This is nasty, since mutt has to wait until gpg is finished
when displaying a gpg signed message (with signature verification on). So I've
written a tool that splits a huge keyring into a lot of smaller keyrings (one
key per keyring) and a shell script to verify signatures, to be used
from within mutt. The former tool is called
latter one is
gpgverify.sh first invokes
gpg --verify as normal and
captures its output. If gpg failed because the key was not found in any
keyring, the script looks if the key is in one of the splitted keyrings, and if
so, reruns gpg with that keyring included. Otherwise the gpg error is returned.
These scripts are still hacky, if you want to use them you'll probably have to modify them a bit. They aren't too big, so this shouldn't be too much of a problem.
