You are right. If you include an interface in /etc/networking/interfaces, 
NetworkManager should ignore it (when you use ifupdown plugin). You can verify 
that in the logs (/var/log/daemon.log) or by nm-tool.

The configuration is described in manual page:
man NetworkManager.conf

What's in your NetworkManager.conf?
