icegridadmin segfaults with malformed descriptor

By accident came across this obscure bug.

icegridadmin segfaults when loading an application descriptor with nested server instances.

<icegrid>
    <application name="TestSystem">

        <server-template id="sometemplate">
            <server id="someid" exe="/some/path" activation="manual">
                <adapter name="someadapter" register-process="true" id="someid"/>
            </server>
        </server-template>

        <node name="s">
            <server-instance template="sometemplate">
                <server-instance template="sometemplate"/>
            </server-instance>
        </node>

    </application>
</icegrid>

Thanks for the report. What version of Ice and OS did this occur with?

Ice-3.3.1 on Linux.
