Import of RDF fails

If I export some references in Zotero RDF, then I try to import them back, import fails with a message "Impossible to find search engine for the selected file" (or similar: Italian interface). Debian lenny, Firefox/Iceweasel Zotero rc3
The rdf file is available if necessary for testing.
  • Sorry -am I the only one having this problem? It is *very* serious to me (I am no longer able to share my references with others, and I'm trapped in).
  • Upgraded to rc5, now working.
    Thanks a lot!
