Package: libqt5x11extras5 Followup-For: Bug #802811 Dear Maintainer,
I confirm this problem too. After upgrading libqt5x11extras5 to 5.5.1-2 today on Stretch, sddm doesn't start and the Plasma 5 session doesn't start either, also if launched with another display manager. Using openbox I also found out that Kate and Konsole segfault. Downgrading libqt5x11extras5 to 5.4.2-2+b1 is a workaround that prevents this issue. This is what dmesg shows when Plasma 5 starts and immediately fails: drkonqi[1036]: segfault at 0 ip 00007f54f7395a74 sp 00007fffc23c0330 error 4 in libxcb.so.1.1.0[7f54f738b000+21000] drkonqi[1043]: segfault at 0 ip 00007f18756c9a74 sp 00007ffd441dc380 error 4 in libxcb.so.1.1.0[7f18756bf000+21000] drkonqi[1048]: segfault at 0 ip 00007fd1d3ca6a74 sp 00007fff5846ea10 error 4 in libxcb.so.1.1.0[7fd1d3c9c000+21000] Best regards Francesco -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.2.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=it_IT.UTF-8, LC_CTYPE=it_IT.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libqt5x11extras5 depends on: ii libc6 2.19-22 ii libqt5core5a 5.4.2+dfsg-9 ii libqt5gui5 5.4.2+dfsg-9 libqt5x11extras5 recommends no packages. libqt5x11extras5 suggests no packages. -- no debconf information
