Here ya go, about as minimal as I can imagine:

    \setupbackend [export=yes]
    \setupexport  []
    \starttext
    !
    \stoptext

and in the resulting export styles directory, I get:

    g:\yoiks-export\styles>grep "namespace\|weight.*italic\|text-width" *.css
    yoiks-defaults.css:@namespace context url('http://www.pragma-ade.com/context/export') ;
    yoiks-defaults.css:     font-weight : italic ;
    yoiks-images.css:@namespace context url('%namespace%') ;
    yoiks-styles.css:@namespace context url('%namespace%') ;
    yoiks-styles.css:    text-width : justify !important ;
    yoiks-templates.css:@namespace context url('%namespace%') ;

So:

  * three unexpanded %namespace%s,
  * one invalid property (text-width),
  * and one incorrect property (font-weight should be font-style).

        This should probably be:

        url('<a class="moz-txt-link-freetext" href="http://www.pragma-ade.com/context/export">http://www.pragma-ade.com/context/export</a>') ;
        <br>
        <br>
        That file also has:
        <br>
        <br>
            document,
        <br>
            %namespace%div.document {
        <br>
                 font-size  : %size% !important ;
        <br>
                 max-width  : %width% !important ;
        <br>
                 text-width : %align% !important ;
        <br>
                 hyphens    : %hyphens% !important ;
        <br>
            }
        <br>
        <br>
        which contains the invalid css property text-width. Perhaps that
        should be text-align or text-justify.
        <br>
        <br>
        Something else appears to be creating, in \jobname-defaults.css:
        <br>
        <br>
            pubfld[detail="title"],
        <br>
            div.pubfld.title {
        <br>
                 display     : inline ;
        <br>
                 font-weight : italic ;
        <br>
            }
        <br>
        <br>
        which incorrectly assigns italic to font-weight when of course
        it  is a font-style as far as css is concerned. This can be seen
        in file export-example.css in the distribution.<br>
