[Tex/LaTex] “Missing $ inserted” error in bibliography, no underscores

biberbiblatexbibliographiescompilingerrors

When I compile my thesis the following error pops up:

Underfull \hbox (badness 1264) in paragraph at lines 61--61
[]\T1/ppl/m/n/12 ^^U^^U^^U.^^P  Naples 2008, or, the Waste Land: Trash, Citizenship, and an Ethic of
[106]
! Missing $ inserted.
<inserted text> 
            $
l.61

This happens in latexmk, or in pdflatex after I run biber. Other posters reporting the same error often nail it down to an underscore in the bibtex entry, but this is clearly not the case here:

@ARTICLE{iovino2009naples,
  author = {Iovino, Serenella},
  title = {Naples 2008, or, the Waste Land: Trash, Citizenship, and an Ethic of Narration},
  journaltitle = {Neohelicon},
  year = {2009},
  date = {2009-09},
  volume = {36},
  issue = {2},
  pages = {335--346},
  doi = {http://dx.doi.org/10.1007/s11059-009-0004-6},
  url = {http://www.springerlink.com/index/10.1007/s11059-009-0004-6},
  file = {iovino2009naples.pdf:iovino2009naples.pdf:PDF},
  pdf = {iovino2009naples.pdf}
}

What is happening? What can I do?

[EDIT] Here's a MWE as requested:

\documentclass[12pt, a4paper, twoside, openright, draft]{book}
\usepackage{hyperref}
\usepackage[style=mla,mladraft=true,backend=biber,bibencoding=utf8]{biblatex}
\bibliography{../bibtex/workscited.bib}
\begin{document}
\autocite{iovino2012wilderness}
\printbibliography
\end{document}

Where the iovino2012wilderness entry is:

@INBOOK{iovino2012wilderness,
  author = {Iovino, Serenella},
  title = {The Wilderness of the Human Other: Italo Calvino's 'The Watcher' and a Reflection on the Future of Ecocriticism.},
  booktitle = {The Future of Ecocriticism},
  year = {2012},
  date = {2012},
  editor = {Serpil Oppermann, Ufuk \"{O}zda\breve{g}, Nevin \"{O}zkan and Scott
    Slovic},
  urldate = {2012-12-09},
  file = {iovino2012wilderness.pdf:iovino2012wilderness.pdf:PDF},
  pdf = {iovino2012wilderness.pdf},
  shorttitle = {The Wilderness of the Human Other}
}

This still produces errors:

Missing $ inserted \end
You can't use `\spacefactor' in math mode \end
Missing $ inserted \end

Best Answer

This one was due to the \breve{g}. Eliminating it lets me compile the document. I am using \u{g} instead.
