<p>This seems like a bug to me. I'm not all too familiar with the code, but in /app/views/layouts/_search.html.erb I see</p>

<div class="highlight highlight-erb"><pre> <<span class="pl-ent">span</span> <span class="pl-e">class</span>=<span class="pl-s"><span class="pl-pds">"</span>force_width<span class="pl-pds">"</span></span>><span class="pl-pse"><%=</span><span class="pl-s1"> text_field_tag <span class="pl-s"><span class="pl-pds">"</span>route_from<span class="pl-pds">"</span></span>, params[<span class="pl-c1">:from</span>], <span class="pl-c1">:placeholder</span> => t(<span class="pl-s"><span class="pl-pds">'</span>site.search.from<span class="pl-pds">'</span></span>) </span><span class="pl-pse"><span class="pl-s1">%</span>></span></<span class="pl-ent">span</span>>
(...)
 <<span class="pl-ent">span</span> <span class="pl-e">class</span>=<span class="pl-s"><span class="pl-pds">"</span>force_width<span class="pl-pds">"</span></span>><span class="pl-pse"><%=</span><span class="pl-s1"> text_field_tag <span class="pl-s"><span class="pl-pds">"</span>route_to<span class="pl-pds">"</span></span> , params[<span class="pl-c1">:to</span>] , <span class="pl-c1">:placeholder</span> => t(<span class="pl-s"><span class="pl-pds">'</span>site.search.to<span class="pl-pds">'</span></span>) </span><span class="pl-pse"><span class="pl-s1">%</span>></span></<span class="pl-ent">span</span>></pre></div>

<p>I don't know Ruby so please don't shoot me, but could it have to do with the space after <code>params[:to]</code>?</p>
