Hi. FYI, the problem still happened again after a while, and upgrading to evolution 2.4.2.1 doesn't seem to solve the issue.
Reported upstream for 2.4.2.1 in http://bugzilla.gnome.org/show_bug.cgi?id=331281 Regards, -- Olivier BERGER <[EMAIL PROTECTED]> Ingénieur Recherche - Dept INF INT Evry (http://www.int-evry.fr) OpenPGP-Id: 1024D/6B829EEC
