Ok, new updates over the weekend. Just tested it on one server, with the result that I think there's a bug with the thunderbird package. As in, Updating : thunderbird 10/28 Could not parse file '/usr/share/applications/redhat-userpasswd.desktop': desktop entry does not have group 'Desktop Entry' So, someone's got their cases wrong, or they forgot to put an ignore case flag on. Should I file a bug report? mark
