[Bug 1891740] Re: Indicator Applet Crashes with unity::indicator::datetime::DateTime::get() const: assertion failed: (m_dt)
Thanks iPadGuy, I can confirm that task creation via Evolution triggers the issue. After following your instructions and relaunching the indicator-datetime service, the indicator correctly reappeared in the indicator tray. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891740 Title: Indicator Applet Crashes with unity::indicator::datetime::DateTime::get() const: assertion failed: (m_dt) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-datetime/+bug/1891740/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1891740] Re: Indicator Applet Crashes with unity::indicator::datetime::DateTime::get() const: assertion failed: (m_dt)
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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891740 Title: Indicator Applet Crashes with unity::indicator::datetime::DateTime::get() const: assertion failed: (m_dt) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-datetime/+bug/1891740/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

After investigating a bit more, the issue is probably that `e_cal_component_get_dtstart` returns a nullptr for a call in get_appointment in EdsEngine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891740 Title: Indicator Applet Crashes with unity::indicator::datetime::DateTime::get() const: assertion failed: (m_dt) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-datetime/+bug/1891740/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I added some debugging output to the DateTime class to create stacktrace when a DateTime is assigned whose `m_dt` field is a `nullptr`.
