Subject: [PATCH] event-editor: Fix possible use-after-free of recurrence until
|
|
date
|
|
|
|
The GcalDateSelector returns an internal instance, while the 'until' date/time
|
|
is meant to be an own instance, which is freed by the GcalRecurrence instance
|
|
in its free function. That means the 'until' date/time is supposed to be reffed
|
|
when being assigned into the GcalRecurrence structure.
|
|
|
|
Closes https://gitlab.gnome.org/GNOME/gnome-calendar/-/issues/892
