When you say "a" sef plugin? Do you mean you enabled the one that comes with Joomla!?

Under that I mean ARTIO JoomSEF.

Unfortunately, no the problem does not disappear - turning this component on and off was my first action (sorry for not specifying).
Mystery solved. For reasons beyond my understanding, the template index file was missing one line: <jdoc:include type="head" />.

Thanks mcsmom !
