Indeed, those packages had different versions:

Code Select
$ dpkg -l|grep libcurl4-gnutls:amd64
ii  libcurl4-gnutls:amd64                                    8.22.0-1                                  amd64        easy-to-use client-side URL transfer library (GnuTLS flavour)

 $ dpkg -l|grep libselinux1:amd64
ii  libselinux1:amd64                                        3.11-2                                    amd64        SELinux runtime shared libraries

So, I just did another full-upgrade and now they seem to match:

Code Select
$  dpkg -l|grep libcurl4-gnutls:amd64
ii  libcurl4-gnutls:amd64                                    8.23.0~rc1-2                              amd64        easy-to-use client-side URL transfer library (GnuTLS flavour)

$  dpkg -l|grep libselinux1:amd64
ii  libselinux1:amd64                                        3.11-2.1                                  amd64        SELinux runtime shared libraries

By krunner (and the plasmashell) still fail to start... :-(

The error message was a bit different, though, and shows some QML related issue (it seems):

Code Select
$ krunner

Here is a new GDB back trace:
