New installation of Update Manager gives the following when I try to download the Joomla update:

Fatal error: Call to a member function name() on a non-object in /home/serida/public_html/joomla15/administrator/components/com_jupdateman/step1.php on line 54

I recall trying to use this about 6-8 weeks ago with similar issues and couldn;t get it resolved then.

Joomla is still at 1.5.10 (if that is affecting it) and running on php v5.2.8 so, AFAICS, all version requirements are met.

ANy ideas please?
