Lots of warnings after GcalTimeline work
After the original GcalTimeline work was merged, I now see a huge number of warnings when switching back and forth between months in month view. To reproduce, I have to navigate back four months from April to March, then to February, then to January, then to December, using the back button in month view. Then I see exactly one warning. Then I navigate forward again back to January, and I get tons of warnings. They come in three forms. Lots of these:
(gnome-calendar:68598): GcalMonthView-WARNING **: 16:56:13.435: gcal_month_view_remove_event: Widget with uuid: 8a780b3679ecd930c10a0b4eb5ecad836c14ae17:2dgkn1ru4o7qilpma64aeni984_R20200319T150000@google.com:20200430T110000 not found in view: GcalMonthView
Lots of these:
(gnome-calendar:68598): GcalWeekHeader-WARNING **: 16:56:16.684: Error adding event 'Cinco de Mayo' to the week header
And lots of these:
(gnome-calendar:68598): GcalMonthView-WARNING **: 16:56:16.803: Event with uuid: 8a780b3679ecd930c10a0b4eb5ecad836c14ae17:2dgkn1ru4o7qilpma64aeni984_R20200319T150000@google.com:20200430T110000 already added
I think all three warnings are regressions from the GcalRange work. These did not occur after the original timeline work was merged.
