Bug#153320: tetex-extra: Package hyperref Warning: bookmark level for unknown xchapter defaults to 0.

Here's what I have found necessary:

  \ifwanthyperref       % horrid incompatibility
  \usepackage{hyperref}
  % \usepackage{minitoc_href}
  \usepackage{minitoc-hyper}
  \makeatletter\def\toclevel@xchapter{0}\makeatother  % should be 
  \makeatletter\def\toclevel@xpart{-1}\makeatother  % should be 
  \else
  \usepackage{minitoc}
  \fi

This makes the warning disappear; I don't use PDF so I can't speak to
the other.

Thanks!

No, I haven't.
