Underfull \hbox (badness 10000) (\makecvtitle)

[bienchen]

Using the \makecvtitle command, I get an 'underfull \hbox' warning. Seems to be issued by the end of the command's definition. If adding a '\null\hfill' before the '\par' for the casual style seems to fix this.

Here is my slightly modified version of the command:

\renewcommand*{\makecvtitle}{%
  % recompute lengths (in case we are switching from letter to resume, or vice versa)
  \recomputecvlengths%
  % ensure footer with personal information
  \makecvfooter%
  % optional picture
  \newbox{\makecvtitlepicturebox}%
  \savebox{\makecvtitlepicturebox}{%
    \ifthenelse{\isundefined{\@photo}}%
      {}%
      {%
       \setlength\fboxrule{\@photoframewidth}%
       \ifdim\@photoframewidth=0pt%
         \setlength{\fboxsep}{0pt}\fi%
       {\color{color1}\framebox{\includegraphics[width=\@photowidth]{\@photo}}}}}%
  \usebox{\makecvtitlepicturebox}%
  % name
  \@initializelength{\makecvtitlepicturewidth}%
  \settowidth{\makecvtitlepicturewidth}{\usebox{\makecvtitlepicturebox}}%
  \parbox[b]{\textwidth-\makecvtitlepicturewidth}{%
    \raggedleft\namefont{\color{color2!50}\@firstname} {\color{color2}\@lastname}}\\[-.35em]% alternate design: \MakeLowercase and no space
  {\color{color2!50}\rule{\textwidth}{.25ex}}%
  % optional title
  \ifthenelse{\equal{\@title}{}}{}{\\[1.25em]\null\hfill\titlestyle{\@title}}\\[2.5em]% \null is required as there is no box on the line after \\, so glue (and leaders) disappears; this is in contrast to after \par, where the next line starts with an indent box (even after \noindent).
  % optional quote
  \ifthenelse{\isundefined{\@quote}}%
    {}%
    {{\null\hfill\begin{minipage}{\quotewidth}\centering\quotestyle{\@quote}\end{minipage}\hfill\null\\[2.5em]}}\null\hfill%
  \par}% to avoid weird spacing bug at the first section if no blank line is left after \maketitle
