[EventCalendar] plasmashell crashes with gcal enabled

[progwolff]

Might be related to #60.
Having google calendar enabled, plasmashell crashes each time I try to open the plasmoid from the task panel.

Version 47, Plasma 5.10, Arch Linux 4.11.9-1-ck

I assume you're using qt5-base 5.9.1-2. Did you recently update qt? What version was it previously?

What makes you think it's emoji related? Do you have emojis in your event titles (or possibly elsewhere)?

#10 0x00007ffff4dc47ee in QQmlListModel::clear() () at /usr/lib/libQt5Qml.so.5

That line points to some wackyness in clearing the agenda list (before updating it).

• https://github.com/Zren/plasma-applets/blob/master/org.kde.plasma.eventcalendar/package/contents/ui/AgendaView.qml#L144

or the event listmodel when fetching the events

• plasma-applets/org.kde.plasma.eventcalendar/package/contents/ui/EventModel.qml

  Line 132 in d531aea

  clear()

However I don't think it's the event listmodel since we use that to check for upcoming events (to show a notification) when the widget is loaded (before you open it). So it's probably the agenda list.

I'm using qt5-base 5.9.1-2, yes.

Actually, this issue persists since several months (maybe since updating to plasma 5.9?). It's not related to a specific version of Qt.

I just noticed there were some files in ~/.local/share/plasma/plasmoids/org.kde.plasma.eventcalendar that had not been updated. Removed this directory and restarted plasmashell. Now everything works fine.

Sorry for bothering you with this and thanks for this great plasmoid!

Ah, so you were using an older version in ~/.local/share/... (installed via get hot new stuff) that overloads the plasma5-applets-eventcalendar which installs to /usr/share/.... Glad you got it fixed!
