I have found out what was causing this - the zip file that is available 
for download cannot be imported directly, you have to unzip it first!

Then you get an SQL script to run to create the necessary tables, and 
another zipfile, which is what needs to be imported using the module 
manager.

So, I've now managed to import this module, and I restarted Tomcat, but I
still get errors in that the title in the Admin view dowsn't appear to be
correct (??? com_opencms_modules_homepage_news_NewsBackoffice.icon.news
???) and whn I click on this, I get the following error:

com.opencms.core.CmsException: 26 Wrong XML template class. Detailed 
error: Could not initialize (sub-)element for class 
"com.opencms.modules.homepage.news.NewsBackoffice".
