Package: libxi6 Version: 2:1.7.8-1 Severity: important Dear Maintainer,
after upgrading libxi6 from 2:1.7.6-1 to 2:1.7.8-1 the ksmserver crashes when closing lid and desktop should lock. Downgrade to the older version helps and it happens every time. See the backtrace. When ksmserver crashes, the whole session is terminated, so it is quite unplesant crash. Thank you. -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (800, 'unstable'), (700, 'testing'), (600, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.8.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=cs_CZ.UTF-8, LC_CTYPE=cs_CZ.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
