axis2_amqp_server doesn't run when transportReceiver is enabled

We are testing the amqp support in Axis2/C. We successfully configured built Axis2/C 1.7.0 source codes from the SVN Trunk with amqp enable

./configure --with-apache2=/usr/local/apache2/include/ --with-apr=/usr/local/apr/include/apr-1/ --enable-openssl=yes --enable-tcp=yes --with-qpid=/usr/local

and successfully generated axis2_amqp_server in $AXIS2C_HOME. However, when we add these lines in axis2.xml (according to the manual http://axis.apache.org/axis2/c/core/docs/axis2c_manual.html#amqptrans)

<transportReceiver name="amqp" class="axis2_amqp_receiver">
<parameter name="qpid_broker_ip" locked="false">127.0.0.1</parameter>
<parameter name="qpid_broker_port" locked="false">5672</parameter>
</transportReceiver>

<transportSender name="amqp" class="axis2_amqp_sender"/>

the server didn't start. We also ran it through gdb. axis2.log and gdb trace are below.
