Critical warnings from the AdwWindow when using the ICS calendar event importer dialog
When opening an ICS file in GNOME Calendar, I see the following criticals:
(gnome-calendar:228827): GLib-GObject-CRITICAL **: 12:20:06.110: g_object_new_is_valid_property: object class 'GcalImportDialog' has no property named 'use-header-bar'
(gnome-calendar:228827): GLib-CRITICAL **: 12:20:06.119: g_ptr_array_ref: assertion 'array' failed
Normally I would take a backtrace to the first one, but I think you don't need one this time. Just grep for use-header-bar
