Bug#916396: caldav free-busy query is broken

[Jamie McClymont]

Package: evolution-data-server
Version: 3.30.2-2

A couple of bugs are present which make CalDAV scheduling effectively
useless - the combined effect of them is that everyone else shows as
having your availability information, rather than their own.

I have patched the bugs upstream, and they have been merged into the
branches for both 3.30.4 and 3.31.4:

* https://gitlab.gnome.org/GNOME/evolution-data-server/merge_requests/8
* https://gitlab.gnome.org/GNOME/evolution-data-server/merge_requests/7

I'm hoping these patches could either be backported to the version in
Buster before it's frozen, or buster can update to 3.30.4 when it is
released.


I have also submitted a patch downstream in Ubuntu Bionic, which
backports to the older version of evolution they are packaging:
