SUMMARY For me, the fix was to delete a recently-created task in Evolution.
DETAILS I encountered this error a few hours ago, after I added a task in Evolution (something I rarely do). I set three reminders for the task. Within 10 minutes, the datetime indicator applet froze at 16:40. The Date tab in the Date/Time settng applet was also greyed-out, so I was unable to turn it back on. I re-booted three times, hoping it was an update issue, but all I saw was the datetime indicator crash repeatedly and then vanish within seconds of my logging in. I searched /var/log/syslog for "crash" and found it was the datetime- indicator service that had crashed. I was able to confirm this with the following command: systemctl status indicator-datetime --user I tried restarting it, but I got a message that the service had crashed too many times. Since I was fairly certain that this was related to the Evolution Task that I just created, I deleted it, restarted the service, and the datetime indicator came back. Hopefully, this will help someone else. -- You received this bug notification because you are a member of DX Packages, which is subscribed to indicator-datetime in Ubuntu.
