J'ai reçu un sympathique message de Dmitry S. Makovey qui m'a aimablement écrit: > epm -qf > /usr/kde/3.5/share/apps/ksgmltools2/docbook/xml-dtd-4.1.2/ent/iso-amsn.ent > > kdelibs-3.5.9-r4 > > looks like your problem somewhere with kdelibs and not k3b. Either that or > docbook-sgml-dtd-4.1-r3 IMO. Try to re-merge those two and then k3b.
I re-emerged kdelibs and it worked :-) I didn't understand which the second e-build to re-emerge was. Nevertheless k3b is again working. Thank you very much for your helpfull answer. Roger
