To reproduce:
1. Download fresh copy and install 
2. Edit conf/activemq.xml and change broker line to 
<broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}"
schedulerSupport="true"> 

3. Go to admin console and create a topic, http://localhost:8161/admin/topics.jsp
4. Go to admin console and create durable subscriber to topic above http://localhost:8161/admin/subscribers.jsp
5. Delete the durable subscriber using link on same page and it will fail 

Repeat all steps above but this time set schedulerSupport=false. Then it will delete the durable
without any errors.
