I forked Mu and let it store the “X-Debbugs-Envelope-To” header in the
database:

    
https://git.elephly.net/?p=software/mumimu.git;a=shortlog;h=refs/heads/mumimu

The “bugid” query can be used to quickly retrieve messages belonging to
a certain Debbugs bug, so something like this will print the message
subject for all messages relating to bug 31023.

    (use-modules (mumimu))
    (mu:initialize (%config 'mail-dir))
    (for-each
     (lambda (msg)
       (pk (mu:subject msg)))
     (mu:message-list "bugid:31023"))

This seems to actually work.  Still don’t know if all emails actually
have that header; if they don’t we’ll need to implement an alternative
way to get the bug number in “get_bugid” (lib/mu-msg-file.c).
