It's 'Sean' ;)

Looking at your quilt patch, it looks like this is a fix for a
particular version of htmlize.  The problem is that we don't know
whether later versions of htmlize fix the problem or not (maybe
htmlize-hack.el was written when version 1.34 was the latest version but
the fix was never merged upstream).

I think you need to test muse with your quilt patch and the latest
htmlize and see if things are sane.  If not, you might just have to take
out the htmlize support altogether, until muse gets updated (or you
could write a patch to update muse to not need the hack, and submit it
upstream and apply as a quilt patch).

I don't see any bug in dh_elpa here.  Could you explain what you were
expecting dh_elpa to do that it isn't doing?
