I manually add a entry to the ToC with dots:

\addcontentsline{toc}{chapter}{\itshape{Contributors' Addresses}  \dotfill}


But this generate me a entryin my bookmark with Contributors' Addresses to.44em. Please have a look at the image. I do not know where the to.44em is coming from.

• Second, generally you should not add \dotfill to the entry but redefine the format of the entry redefinining \l@chapter. – Schweinebacke Jan 12 '17 at 11:13
• Third, you can try \texorpdfpdfstring{ \dotfill}{}. – Schweinebacke Jan 12 '17 at 11:14
• I added a MWE, hopefully this helps. \texorpdfpdfstring{ \dotfill}{} do not work – mvp285286 Jan 12 '17 at 12:28
• Is this really minimal??? – Schweinebacke Jan 12 '17 at 12:34
• The "to44em" is the amount of space, which is added between the dotted line and the page number. – Jan Jan 12 '17 at 12:37

You should always protect non robust macros inside \addcontentsline otherwise their expansion will be written to the .aux- and the .toc-file.

To avoid the to.44em in the bookmarks use \texorpdfstring:

  \addcontentsline{toc}{chapter}{Contributors'

You may use package bookmark to have immediate bookmark changes in the first LaTeX run.
BTW: Usage of tocloft and titlesec with scrbook is not recommended.
