I ran into this recently. It seems to be because glade-3 is outputing  
"pattern" as the empty string whereas it needs to be NULL (not in the  
glade file) for GtkLabel to honour markup (or underlining). I just  
added a rule to the xslt file that I use to remove empty patterns.  
Something like this should work (untested):

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform";  
version="1.0"
     xmlns="http://glade.gnome.org/glade-2.0.dtd";
     exclude-result-prefixes="#default">
<xsl:output method="xml" standalone="no"
     doctype-system="http://glade.gnome.org/glade-2.0.dtd"/>

<!-- Elide some default attributes that the DTD introduces -->
<xsl:template match="@context[.='no']"/>
<xsl:template match="@translatable[.='no']"/>
<xsl:template match="@after[.='no']"/>

<!-- Preserve attributes -->
<xsl:template match="@*">
   <xsl:copy/>
</xsl:template>

<!-- Copy -->
<xsl:template match="*">
   <xsl:choose>
     <!-- Drop empty label patterns (from glade-3) which kill markup  
etc. -->
     <xsl:when test="name()='property' and @name='pattern' and  
not(text()) and parent::node()[name()='widget' and @class='GtkLabel']"/
>
     <xsl:otherwise>
       <xsl:copy>
         <xsl:apply-templates select="@*|node()"/>
       </xsl:copy>
     </xsl:otherwise>
   </xsl:choose>
</xsl:template>

</xsl:transform>

HTH,
