Biblatex Bibliography: Suppress “In:” (articles only) and avoid additional punctuation [closed]

Question

Supressing the "In:" in articles in biblatex bibliographies

“Dupe”, some of you might want to say now, and indeed, I want to solve the same problem as @Kit did 1,5 years ago.

However, with biblatex 2.2 and biber 1.2 the code snippet by @Herbert introduces an additional " ." in front of the journal title when compiled with xelatex. It becomes:

Green, Brian (2006). ‘Classing Identity, Identifying Class: Locating Materialist / Deconstructionist Convergence’ . Critical Sociology 32.4, pp. 603–616.

When I compile the minimal example with pdflatex there is only a dot (without a preceding space) introduced.

As I can't comment on the older question, and I think it would be wrong to reply in form of an answer, I deemed this to be the appropriate way to ask for help.

Minimal Example

\documentclass{scrartcl}
\usepackage[backend=biber,style=authoryear-icomp]{biblatex}

   \renewbibmacro{in:}{%
     \ifentrytype{article}{}{%
     \printtext{\bibstring{in}\intitlepunct}}}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@ARTICLE{green06,
  author = {Green, Brian},
  title = {Classing Identity, Identifying Class: Locating Materialist / Deconstructionist
        Convergence},
  year = {2006},
  volume = {32},
  number = {4},
  pages = {603 - 616},
  journaltitle = {Critical Sociology}
}
\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}
\nocite{green06}
\printbibliography
\end{document}
