Package: evolution Version: 3.20.4-1 Severity: important Evolution 3.20.4-2 depends on
"libecal-1.2-19 (>= 3.17)" Hence when I manually upgraded to Evolution 3.20.4-2 (version in "testing") my system was left with libecal-1.2-19 version 3.18.0-3, and in this configuration Evolution would segfault every time I tried to open the preferences window. I noticed that the gdb backtrace referred to libecal, and indeed upgrading libecal-1.2-19 to version 3.20.4-2 immediately fixed the problem. The versioned Depends should hence probably be changed to "libecal-1.2-19 (>= 3.20.4)" -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (650, 'testing'), (600, 'unstable'), (600, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.5.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=it_IT.utf8, LC_CTYPE=it_IT.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages evolution depends on: ii dbus 1.10.0-3 ii evolution-common 3.20.4-1 ii evolution-data-server 3.20.4-2 ii libc6 2.19-22 ii libcamel-1.2-57 3.20.4-2 ii libclutter-gtk-1.0-0 1.6.6-1 ii libecal-1.2-19 3.20.4-2 ii libedataserver-1.2-21 3.20.4-2 ii libevolution 3.20.4-1 ii libglib2.0-0 2.48.0-1 ii libgtk-3-0 3.20.3-2 ii libical2 2.0.0-0.4 ii libicu55 55.1-5 ii libnotify4 0.7.6-2 ii libsoup2.4-1 2.52.1-1 ii libwebkitgtk-3.0-0 2.4.9-2+b1 ii libxml2 2.9.2+zdfsg1-4 ii psmisc 22.21-2.1 Versions of packages evolution recommends: ii bogofilter 1.2.4+dfsg1-3 ii evolution-plugins 3.20.4-1 ii yelp 3.16.1-1 Versions of packages evolution suggests: pn evolution-ews <none> ii evolution-plugins-experimental 3.20.4-1 ii gnupg 1.4.19-5 ii network-manager 1.2.0-1 -- debconf information excluded
