Code review comment for lp://staging/~pkunal-parmar/ubuntu-calendar-app/CalManagement

I have asked Albert if he can help us debug the crash which is easily reproducible with this branch:-

Grab this branch
Add this ppa https://launchpad.net/~popey/+archive/qtpim and update/upgrade
In system system-settings -> online accounts I have 2x google accounts (one personal, one work) which I enabled calendar sync on. (I have also tried with only one account active).
Start the calendar app with qmlscene calendar.qml
After a short while navigating around it crashes:-

(qmlscene:21334): GLib-GObject-CRITICAL **: g_object_unref: assertion
'G_IS_OBJECT (object)' failed
Segmentation fault (core dumped)
