When opening a CBZ file I get the message "doc-view-set-doc-type:
Conflicting types: name says (cbz) but content says (epub odf)".

Looking at the end of `doc-view-set-doc-type` (lisp/doc-view.el:2141)
it's pretty obvious why and it has an easy fix.  In fact we already did
this fix once before for ODF files as you can see at bug#54947 which
resulted in commit b3ff4905388834994ff26d9d033d6bc62b094c1c
