Version: 4.3.0 pre (using 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2)), Kubuntu packages) Compiler: cc OS: Linux (i686) release 2.6.28-13-generic I select in kmail -> configuration -> identity -> cryptography then I try to attach a s/mime certificate for signing or crypting the certificate to attach windows appears my certificate appears in this window when I select it, a red cross appear on the key icon on the left (see attached screenshot) so I cannot select it This certificate is shown as perfectly valid in firefox.
Created attachment 34477 [details] red cross on certificate preventing it to be selected ... and there is no explanation as why this certificate cannot be used.
Happens on 4.4.1 as well. (Gentoo Linux). Kleopatra shows the certificate as valid.
Same thing on 4.4.2.
Actually it's not a bug, this will solve the issue: https://bugs.kde.org/show_bug.cgi?id=192104#c3 HTH.
