There is no bug 1761466, apparently. Some further testing on Ubuntu 18.10 (dev branch) + GNOME 3.30 later: The situation somewhat normalized after removing several applications like GNOME Documents, Weather, To-Do and some others. The tasks in Evolution (and/or GNOME Calendar and the calendar in the notification area) still disappear, but reappear when entering a new task in Evolution. Everything seems back to normal from there, until the issue reoccurs after closing and restarting evolution. Entering a new task makes the other tasks visible again. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-calendar in Ubuntu. https://bugs.launchpad.net/bugs/1796836 Title: gnome-calendar crashed with SIGSEGV in gcal_manager_is_client_writable() Status in gnome-calendar package in Ubuntu: New Bug description: I'm having serious calendar/task issues under Ubuntu+GNOME 18.10b. Evolution losing its calendar/tasks/events settings and not being able to recover by restoring backup data. Then there's GNOME calendar hanging and/or crashing. I tried several things like completely removing all evolution and calendar related data and reinstalling (even manually), but that did not result in a much better outcome either.
