Comment 1 for bug 1200987

The issue is in the file /usr/share/yelp-xsl/xslt/common/html.xsl
here:

div.code {
  background: url('</xsl:text>
    <xsl:value-of select="$icons.code"/><xsl:text>') no-repeat top </xsl:text>
    <xsl:value-of select="$right"/><xsl:text>;
  border: solid 1px </xsl:text>
    <xsl:value-of select="$color.gray_border"/><xsl:text>;
}

where icons.code maps to yelp-code.png from within the file /usr/share/yelp-xsl/xslt/common/icons.xsl

we do not have control over that file, so we will have to override that definition with one in ubuntu.xls.
