Karl,

My mimeTypes.rdf contained only the following lines (after a bunch of
xml comments):

<RDF:RDF xmlns:RDF="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
         xmlns:NC="http://home.netscape.com/NC-rdf#">

  <RDF:Description about="urn:mimetypes">
    <NC:MIME-types>
      <RDF:Seq about="urn:mimetypes:root">
      </RDF:Seq>
    </NC:MIME-types>
  </RDF:Description>
</RDF:RDF>

There also was an identical version of the file in a subdirectory named
"US" in the xxxxxxxx.default directory.  I even completely removed the
.mozilla-thunderbird directory in my home directory, removed and
reinstalled the packages thunderbird, enigmail and lightning-extension. 
I am running kubuntu 9.10 on amd64, and the version of thunderbird that
gets installed is 2.0.0.24.

When I replaced my versions of mimeTypes.rdf with yours (in both
places), the Actions list is no longer empty, but only lists "Open with
okular" for PDF documents.  Even though http and https are listed in the
mimeTypes.rdf file, no corresponding action appears.
