I have attached gdb.txt which is a full backtrace generated as
detailed at http://wiki.debian.org/XStrikeForce/XserverDebugging
although without the benefit of debugging symbols as I did not find an
xfce4-session-dbg package.  I have also attached the xfce4-session.xml
configuration that causes the crashes.

To stop the crashes I remove the following from xfce4-session.xml:

  <property name="splash" type="empty">
    <property name="Engine" type="string" value="balou"/>
    <property name="engines" type="empty">
      <property name="simple" type="empty">
        <property name="Font" type="empty"/>
        <property name="BgColor" type="empty"/>
        <property name="FgColor" type="empty"/>
        <property name="Image" type="empty"/>
      </property>
      <property name="balou" type="empty">
        <property name="Theme" type="string" value="Default"/>
      </property>
    </property>
  </property>
