Sorry, my bad. I don't know where I got 3.08. I've run the updates b300 and b301 on this site, with only b300 on the one which works with the container in the header file.
Also FriendlyURLs are turned on. I've tried placing the import for the container tag library in Application.cfm, with the same effect. When I place it in the header file, however, CF stops processing after the header file.
