When I try to export a document from org-mode in emacs, c-X, c-E now results in 'Can't find library org' whereas in 10.04 it opened the export dialog allowing me to produce html, pdf etc. from the source org file. Searching with Google, I found this bug for redhat which looks closely related. The trouble is I don't know how to get hold of the emacs-el package it talks about in ubuntu in order to try its workaround so I'm currently stuck.
